I maintain a Github repository with currently two ipython notebook files.
My repository is here:
https://github.com/tschm/MosekRegression
When I try to open those files with the nbviewer, e.g. using
nbviewer.ipython.org
and inserting
http://nbviewer.ipython.org/urls/github.com/tschm/MosekRegression/blob/master/Data.ipynb
i get the 400 Bad Request Error. The file is good as it works when I make it available as a Gist. First research seems to indicate that this is a permission problem? I bet I do something stupid here...
Many thanks
Thomas
Expanding on #chuwy's answer, here's a breakdown of steps. The trick is to head to your file's page on github and then click on the "Raw" button:
then copy the url (minus the protocol string "http://"), and prepend it with "http://nbviewer.ipython.org/urls/"
So for example, if I have my iPython notebook:
https://github.com/watsonix/prediction_for_fun_and_profit/blob/master/statsmodel_outliers.ipynb
and I want to see it in the nbviewer, I click on "Raw" to get the URL:
https://raw.githubusercontent.com/watsonix/prediction_for_fun_and_profit/master/statsmodel_outliers.ipynb
which I use to form the URL:
http://nbviewer.ipython.org/urls/raw.githubusercontent.com/watsonix/prediction_for_fun_and_profit/master/statsmodel_outliers.ipynb
voila!
Valid link is http://nbviewer.ipython.org/urls/raw.github.com/tschm/MosekRegression/master/Minimum%20Variance.ipynb
Your link points to the github's html page with your file. You should give the raw file instead.
It now appears that gist automatically renders iPython notebooks! I have been using nbviewer, but I just noticed that GitHub renders the ipynb file perfectly.
Recently I joined GitHub. I hosted some projects there.
I need to include some images in my README File. I don't know how to do that.
I searched about this, but all I got was some links which tell me to "host images on web and specify the image path in README.md file".
Is there any way to do this without hosting the images on any third-party web hosting services?
Try this markdown:
I think you can link directly to the raw version of an image if it's stored in your repository. i.e.
You can also use relative paths like
Also try the following with the desired .fileExtention:
You can create a New Issue
upload(drag & drop) images to it
Copy the images URL and paste it into your README.md file.
here is a detailed youTube video explained this in detail:
https://www.youtube.com/watch?v=nvPOUdz5PL4
It's much simpler than that.
Just upload your image to the repository root, and link to the filename without any path, like so:
You can also add images with simple HTML tags:
<p align="center">
<img src="your_relative_path_here" width="350" title="hover text">
<img src="your_relative_path_here_number_2_large_name" width="350" alt="accessibility text">
</p>
Many of the posted solutions are incomplete or not to my taste.
An external CDN like imgur adds another tool to the chain. Meh.
Creating a dummy issue in the issue tracker is a hack. It creates clutter and confuses users. It's a pain to migrate this solution to a fork, or off GitHub.
Using the gh-pages branch makes the URLs brittle. Another person working on the project maintaining the gh-page may not know something external depends on the path to these images. The gh-pages branch has a particular behavior on GitHub which is not necessary for hosting CDN images.
Tracking assets in version control is a good thing. As a project grows and changes it's a more sustainable way to manage and track changes by multiple users.
If an image applies to a specific revision of the software, it may be preferable to link an immutable image. That way, if the image is later updated to reflect changes to the software, anyone reading that revision's readme will find the correct image.
My preferred solution, inspired by this gist, is to use an assets branch with permalinks to specific revisions.
git checkout --orphan assets
git reset --hard
cp /path/to/cat.png .
git add .
git commit -m 'Added cat picture'
git push -u origin assets
git rev-parse HEAD # Print the SHA, which is optional, you'll see below.
Construct a "permalink" to this revision of the image, and wrap it in Markdown.
Looking up the commit SHA by hand is inconvenient, however, so as a shortcut press Y to a permalink to a file in a specific commit as this help.github page says.
To always show the latest image on the assets branch, use the blob URL:
https://github.com/github/{repository}/blob/assets/cat.png
(From the same GitHub help page File views show the latest version on a branch)
You can also insert animated SVG images in the markdown file like any other format.
It can be a good alternative to GIF images.
OR
<img src="relative/path/in/repository/to/image.svg" width="128"/>
Example (assuming the image is in assets directory in the repository):
Result:
To use different images based on GitHub dark/light theme see this post.
Very Simple : Can be done using Ctrl + C/V
Most of the answers here directly or indirectly involve uploading the image somewhere else & then providing a link to it.
It can be done very simply by just copying any image and pasting it while editing Readme.md
Copying the image - You can just click on the image file and use Ctrl + C or may copy the screenshot image to your clipboard using the snipping tool
You can then simply do Ctrl + V while editing Readme.md
Guithub will automatically upload it to user-images.githubusercontent.com and a link to it will be inserted there
I need to include some images in my README File. I don't know how to
do that.
I created a small wizard that allows you to create and customize simple image galleries for your GitHub repository's readme: See ReadmeGalleryCreatorForGitHub.
The wizard takes advantage of the fact that GitHub allows img tags to occur in the README.md. Also, the wizard makes use of the popular trick of uploading images to GitHub by drag'n'dropping them in the issue area (as already mentioned in one of the answers in this thread).
Commit your image (image.png) in a folder (myFolder) and add the following line in your README.md:
Basic Syntax
Here:
my-image-alt-tag : text that will be displayed if image is not shown.
url-to-image : whatever your image resource is. URI of the image
Example:
This will look like the following:
Create an issue regarding adding images
Add the image by drag and drop or by file chooser
Then copy image source
Now add  to your README.md file
Done!
Alternatively you can use some image hosting site like imgur and get it's url and add it in your README.md file or you can use some static file hosting too.
Sample issue
Just add an <img> tag to your README.md with relative src to your repository. If you're not using relative src, make sure the server supports CORS.
It works because GitHub support inline-html
<img src="/docs/logo.png" alt="My cool logo"/>
# My cool project and above is the logo of it
Observe here
You can now drag and drop the images while editing the readme file.
Github will create a link for you which will be in the format of:
https://user-images.githubusercontent.com/******/********.file_format
Alternatively, at the bottom of the file, it says "Attach files by dragging & dropping, selecting or pasting them". If you click on that one, it will give you an option to upload a file directly or you can just paste it!
You Can use
Where ![A test image] is your alt text and (image.png) is the link to your image.
You can have the image on a cloud service or other online image hosting platforms
Or you can provide the image link from the repository if it is in the repo
You can also make a specific folder inside your repository dedicated to your readme images
Step by step process,
First create a folder ( name your folder ) and add the image/images that you want to upload in Readme.md file. ( you can also add the image/images in any existing folder of your project. )
Now,Click on edit icon of Readme.md file,then
 // refrence_image is the name of image in my case.
After adding image, you can see preview of changes in the, "Preview Changes" tab.you will find your image here.
for example like this,
In my case,
app folder -> src folder -> main folder -> res folder -> drawable folder -> and inside drawable folder refrence_image.png file is located.
For adding multiple images, you can do it like this,
Note 1 - Make sure your image file name does not contain any spaces. If it contain spaces then you need to add %20 for each space between the file name. It's better to remove the spaces.
Note 2 - you can even resize the image using HTML tags, or there are other ways. you can google it for more.
if you need it.
After this, write your commit changes message, and then commit your Changes.
There are many other hacks of doing it like, create a issue and etc and etc. By far this is the best method that I have came across.
Use tables to stand out, it will give separate charm to it
Table Syntax is:
Separate each column cell by symbol |
and table header (First row) by 2nd row by ---
| col 1 | col 2 |
|------------|-------------|
| image 1 | image 2 |
output
Now just put <img src="url/relativePath"> at image 1 and image 2 if you are using two images
Note: if using multiple images just include more columns, you may use width and height attribute to make it look readable.
Example
| col 1 | col 2 |
|------------|-------------|
| <img src="https://media.wired.com/photos/5926db217034dc5f91becd6b/master/w_582,c_limit/so-logo-s.jpg" width="250"> | <img src="https://mk0jobadderjftub56m0.kinstacdn.com/wp-content/uploads/stackoverflow.com-300.jpg" width="250"> |
Spacing does not matter

In new Github UI, this works for me -
Example - Commit your image.png in a folder (myFolder) and add the following line in your README.md:
You can just do:
git checkout --orphan assets
cp /where/image/currently/located/on/machine/diagram.png .
git add .
git commit -m 'Added diagram'
git push -u origin assets
Then you can just reference it in the README file like so:
JUST THIS WORKS!!
take care about your file name uppercase in tag and put PNG file inroot, and link to the filename without any path:
Just README.md file inside write down the code here [Anyname](image path)
Although GitHub markdown can also add pictures I will suggest you use an HTML IMG tag
GitHub Markdown
HTML TAG
<img src='https://github.com/samadpls'/>
I usually host the image on the site, this can link to any hosted image. Just toss this in the readme. Works for .rst files, not sure about .md
.. image:: https://url/path/to/image
:height: 100px
:width: 200 px
:scale: 50 %
I have solved this problem. You only need to refer to someone else's readme file.
At first,you should upload an image file to github code library ! Then direct reference to the address of the image file .
In my case i use imgur and use the direct link this way.
You can link to images in your project from README.md (or externally) using the alternative github CDN link.
The URL will look like this:
https://cdn.rawgit.com/<USER>/<REPO>/<BRANCH>/<PATH>/<TO>/<FILE>
I have an SVG image in my project, and when I reference it in my Python project documentation, it does not render.
Project link
Here is the project link to the file (does not render as an image):
https://github.com/jongracecox/anybadge/blob/master/examples/awesomeness.svg
Example embedded image:
Raw link
Here is the RAW link to the file (still does not render as an image):
https://raw.githubusercontent.com/jongracecox/anybadge/master/examples/awesomeness.svg
Example embedded image:
CDN link
Using the CDN link, I can link to the file using (renders as an image):
https://cdn.rawgit.com/jongracecox/anybadge/master/examples/awesomeness.svg
Example embedded image:
This is how I am able to use images from my project in both my README.md file, and in my PyPi project reStructredText doucmentation (here)
There are 2 simple way you can do this ,
1) use HTML img tag ,
2) 
the path would you can copy from the URL in the browser while you have opened that image.
there might be an issue occur of spacing so make sure if there is any space b/w two words of path or in image name add-> %20. just like browser do.
Both of them will work , if you want to understand more you can check my github -> https://github.com/adityarawat29

I am just extending or adding an example to the already accepted answer.
Once you have put the image on your Github repo.
Then:
Open the corresponding Github repo on your browser.
Navigate to the target image file Then just open the image in a new tab.
Copy the url
And finally insert the url to the following pattern 
On my case it is
Where
shadmazumder is my username
Xcode is the projectname
master is the branch
InOnePicture.png is the image, On my case InOnePicture.png is in the root directory.
In my case I wanted to show a print screen on Github but also on NPM. Even though using the relative path was working within Github, it wasn't working outside of it. Basically, even if I pushed my project to NPM as well (which simply uses the same readme.md, the image was never showing.
I tried a few ways, at the end this is what worked for me:
I now see my image correctly on NPM or anywhere else that I could publish my package.
The Github wikis are backed by a separate git repository then the main project repository.
This post by the Github team makes it sound like you should be able to link to images stored in the wiki repository inside the wiki markup.
Images and Folders
You can now reference images hosted inside the Git repository.
I've checked out my wiki's repository and pushed a resource folder and an image into it. My question is, how do I go about using this image?
Is this even possible or have I misunderstood something?
For viewers wishing to view images on a github wiki I've found the following method to work:
Go to the "Git Access" tab inside the wiki page of your repository and retrieve the SSH path which should be some thing like: git#github.com:USER/REPO.wiki.git where USER is your account name and REPO is the repository name.
On your local machine use whichever Git command line tool you wish to cd into your local directory of choice and get the repository via
git clone git#github.com:USER/REPO.wiki.git
Now within this repository create an image directory, I'll call it "images" and put whatever images you want into the directory
And then push your wiki git directory to github
You will not be able to physically see the images in say the "Pages" tab, but if you simply reference the images in a local link you should be able to see them. Example with Markdown below:
You may also embed the image as a link itself by wrapping it further like so:
[](http://Yoursite.com)
You can also add subdirectories within your local copy to help organize the wiki since the "pages" tab simply lists them out. Keep in mind, however, that even when the new directory is pushed the "pages" tab doesn't list the directory.
To use relative paths do:
[[foo.jpg]]
For more info, see the demo wiki's page on images.
None of answers seem to work when adding an image in readme.md. I've got a solution though:
If the URL of the image is:
https://github.com/Username/Repository-Name/blob/master/Directory-Inside-Repository/image.png
Replacing blob with raw gives you the URL of the raw image:
https://github.com/Username/Repository-Name/raw/master/Directory-Inside-Repository/image.png
Now, you'd embed the image using normal markdown:
UPDATE: As of now, GitHub also serves raw images from a different sub-domain raw.github.com. So, you can also use:
https://raw.github.com/Username/Repository-Name/master/Directory-Inside-Repository/image.png
EXAMPLE: https://raw.github.com/Automattic/liveblog/master/screenshot-1.png
Relative path work for me like this:
home page of the wiki:
sub page of the wiki:
Note that when doing a preview the image will not show, I had save it.
If you want to quickly upload an image with drag/drop, you can perform the following (albeit hackish):
Create a dummy issue; drag & drop your image there; copy/paste the uploaded markdown image code to your wiki;
After you create the issue once, you can use it any number of times to do this.
Hope this helps anyone looking for a quick fix, without needing to have the image reside in the repo.
Here is a practical way to do it:
Go to any issue on github
In the comment section you can attach files, just drag/drop, select or paste your image
Copy the code/link displayed in the textarea
Paste it in the wiki
Profit !
You don't even have to create or modify any issue compared to #tiby solution !
Figured it out.
The url is formatted as follows
https://raw.github.com/wiki/username/project/pathtoimage/imagename.extension
pathtoimage is optional
James' URL format did not work for me, perhaps it has been changed. I have used:
https://github.com/username/project/wiki/pathtoimage/image.extension
Where pathtoimage is optional.
Finally got the images into repository using the method described by nerdwin and got them to display in the wiki using 
The following markdown will reference an image in your GitHub repo from within your corresponding GitHub wiki
The above example assumes that you have the following file structure in your repo
Path
ToAssets
In
Repo.png
For a real world example, if I wanted to reference this image in github from the corresponding wiki, I'd use this markdown
Caveats
Case matters
If you are on the special Home page of the wiki, you do not need to go up a level with the ../ In my example above, the correct link would be
For Home Page:
Use the relative path
the Wiki is located at [repositoryname]/wiki
The files in the repository are located at [repositoryname]/raw/master/[file path in repository]
So just use the relative path: ../raw/master/[file path in repository]
I put both images and PDFs in my wikis. I clone the wiki and add an images and a files directory, then use the following markdown to embed image links and add file links:
Images:
[[/images/path/to/image.ext|ALT TEXT]]
The leading slash isn't necessary if your wiki pages are all at the root level, but I use subdirectories and an absolute path resolves correctly and keeps things simple.
Files:
[link text](files/path/to/file.ext "ALT TEXT")
Note, no leading slash for the wiki files path to resolve correctly as a link in this format.
I documented this with more detail in a GitHub gist
Since Feb. 2022, you can simply drag and drop, select or paste the file.
That will upload the image to your Wiki pages, and store it in https://user-images.githubusercontent.com
To embed an external image thumbnail, use the following,
The comment from #Drew Noakes to the original question did it for me:
The syntax for the image I wanted to be displayed:
[[/images/imageName.png]]
This image was only displayed when renaming:
wikiPage.md --> wikiPage.wiki
The following folder structure was used in the wiki repository:
repository.wiki
|--wikiPage.wiki
|--images
|--imageName.png
BUT:
The syntax in .wiki differs from .md files.
Many of the answers didn't work for me, here's what finally worked:
Using the "Markdown" editor mode and a sub-page such as:
https://github.com/project/repo/wiki/MyPage
