I Have seen several posts regarding this feature to preview HTML file on GitHub. Some suggest prepending https://htmlpreview.github.io/ before the real URL and some suggestions to create GitHub pages that I don't want to do now because then I have to re-create most of the thing on .yml
But my confusion is why this link showing HTML preview but not mine when I prepend the same string on my repo's HTML page. Please let me know If any other way I can see the HTML preview on github
Working:

Check these steps:
-Your repository is public.
(Settings>General>Danger Zone>Change repository visibility>Make public)
-The size of the files are not very large.
-The Repository link is in HTTPS and not in SSH.
EDIT:
I found this question about the private repository and preview, if you want to take a look.
When your html file is excessively big then often github may fail to open the file. In such cases you can check the raw version of the HTML file.
Recently I joined GitHub. I am hosted some projects there.
I need to include some my GoogleDrive images in my README File. I don't know how to do that.
First, get a share-able link to your Google Drive image so anyone can view it.
Then, the GitHub-flavored markdown for an image is what you're looking for:
This is the syntax for an image to be loaded from a link. My favorite example:
I even added a public example for you here on my GitHub
I was just reading this elasticsearch link. I found edit option with every heading which was redirecting me to GitHub website. I know git provides wiki option with every account but that is hosted on GitHub only and supports limited features.
How can I make documentation like this that is linked to GitHub?
It looks like they're using AsciiDoc and just put the repository on Github.
The edit links don't appear to be a special feature of AsciiDoc. They're simple URLs of the form https://github.com/<owner>/<repo>/edit/5.x/<path>. Presumably someone regenerates the site after they accept a pull request.
This will work with most site generation tools, it doesn't appear to be anything specific to AsciiDoc.
I read:
https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/nest-getting-started.html
Then I want edit, it redirect to:
https://github.com/elastic/elasticsearch-net/edit/5.x/docs/client-concepts/high-level/getting-started.asciidoc
Link source code:
https://github.com/elastic/elasticsearch-net/blob/5.x/docs/client-concepts/high-level/getting-started.asciidoc
URL file:
elasticsearch-net/docs/client-concepts/high-level/getting-started.asciidoc
The different is URL parameter: edit and blob. How to create documentation linked with GitHub? So simple, use this convention when create static document file.
I migrated with a project from Bitbucket to GitHub and I cannot find a way to attach a file to an issue (ex: screenshot, specs, etc).
How to do it?
You upload it somewhere and add the link in a comment. GitHub's Issues is rather primitive and doesn't allow attaching files.
Update: You can post images to GitHub issues now. The easiest way is to copy the image (right click, Copy image) and then paste it into the text box where you describe the issue.
OR
Just drag and drop
As of December 7, 2012, you can attach images by drag/drop or use a file chooser. See https://github.com/blog/1347-issue-attachments for more details.
To attach a file to an issue or pull request conversation, drag and drop it into the comment box.
The maximum size for files is 25MB and the maximum size for images is 10MB.
ZenHub.io Chrome plug-in will enable you to add any type of file to a github issue. It's stored on ZenHub's AWS server instead of github.com. From their website...
GitHub only allows you to upload image files. ZenHub adds the ability
to upload any type of file into issues and comments, transferring
securely to Amazon S3. With this you can really take your workflow to
the next level; try using GitHub for everything! Centralized
collaboration and transparency are awesome.
Update:
As of 11/03/2015 you can now upload these types of files to github without any extension or plug-in: PNG, GIF, JPG, DOCX, PPTX, XLSX, TXT, or PDF
As an illustration of the previous answers, see this comment:
I create a repository called catfood http://github.com/blueheadpublishing/catfood/ where I keep misc stuff (like screenshots and other attachments).
That way I can reference them in issues.
See https://github.com/blueheadpublishing/bookshop/issues/10
Some images showing the types of layout templates we want to have generated by templates:
Example One - Three Percentage Columns
Example Two - Two Percentage Columns Left
Example Three - Two Percentage Columns Right
Back in 2009, GitHub expressed the intent to add attachment to issues.
Attachments are something we'd like to add.
That topic wasn't raised since in the GitHub group though...
The format for embedding images into a GitHub comment is:
Format: 
Example: 
Use gist.github.com to upload any contents like code, log, html files etc. and share the link.
It's a bit of a kludge but you could create a junk branch, then commit the file to that branch and purge it later.

I found an easy way to embed images in issues using Skitch. Just set up Skitch sharing and auto-copy the URL to the clipboard. Then paste it in when writing up the issue. I blogged about it here.
One quick/easy hack is to upload your attachment (say PDF or Office doc) to Dropbox, then include the Dropbox URL in the Github issue.
Mildly easier than using S3; many organizations are already using Dropbox; and Dropbox has good support for viewing many documents inline in the browser already.
8 years later (Dec. 2020), you can not only drag and drop images to PR/issues, but also... videos!
And in May 2021, this is now generally available.
Video upload public beta
You can now upload .mp4 and .mov files to issue, pull request, and discussion comments to share reproduction steps, design ideas, and experience details with your team.
The public beta will gradually rollout to all GitHub accounts over the coming week.
OK, here's what I use for screenshots.

It's free, fast, automatically uploads the image and pastes a URL link to your clipboard which you can Ctrl-V into the GitHub issue instantly.
It was a big sigh of relief when I discovered this :)
If your image is already uploaded to github, then you can attach raw link to issues. For example, if your image's location in github is:
https://github.com/Qlio/someproj/blob/master/assets/image.png
then you can can change blob to raw like this:
https://github.com/Qlio/someproj/raw/master/assets/image.png
and then you can use this link to show image:
I have a document that I would like to reference from a github issue, but there is not a way to upload it. Any ideas?
You can't currently attach files to github issues.
Update:
As of 2012-12-07, images can be attached to issues via drag-and-drop.
Just drag the image into the text field for the issue.

If you have an account in github, then you can upload your document in Github's own Gist service: gist.github.com
After add the link in a comment of issue.
I think this will help you
