So, here's my code:
<meta property="og:description"
content="OnlyInStanCo is a site created so people can share their complaints, praise, or stories about what it's like to live in, grow up in, work in, or anything else in the black hole affectionately known as StanCo. ">
I've ran the linter tool on the site, but it still pulls an old description.
Any ideas?
Send your URL to the form on https://developers.facebook.com/tools/debug
It should reset cached meta information and also debug your page.
Add xmlns:fb="http://ogp.me/ns/fb#" to your <html> opening tag, just before the <head> tag in your HTML document. This solved my problem.
e.g. <html xmlns:fb="http://ogp.me/ns/fb#">

When using Facebook Sharer, Facebook will offer the user the option of using 1 of a few images pulled from the source as a preview for their link. How are these images selected, and how can I ensure that any particular image on my page is always included in this list?
How do I tell Facebook which image to use when my page gets shared?
Facebook has a set of open-graph meta tags that it looks at to decide which image to show.
The keys one for the Facebook image are:
<meta property="og:image" content="http://ia.media-imdb.com/rock.jpg"/>
<meta property="og:image:secure_url" content="https://secure.example.com/ogp.jpg" />
and it should be present inside the <head></head> tag at the top of your page.
If these tags are not present, it will look for their older method of specifying an image: <link rel="image_src" href="/myimage.jpg"/>. If neither are present, Facebook will look at the content of your page and choose images from your page that meet its share image criteria: Image must be at least 200px by 200px, have a maximum aspect ratio of 3:1, and in PNG, JPEG or GIF format.
Can I specify multiple images to allow the user to select an image?
Yes, you just need to add multiple image meta tags in the order you want them to appear in. The user will then be presented with an image selector dialog:
I specified the appropriate image meta tags. Why isn't Facebook accepting the changes?
Once a url has been shared, Facebook's crawler, which has a user agent of facebookexternalhit/1.1 (+https://www.facebook.com/externalhit_uatext.php), will access your page and cache the meta information. To force Facebook servers to clear the cache, use the Facebook Url Debugger / Linter Tool that they launched in June 2010 to refresh the cache and troubleshoot any meta tag issues on your page.
Also, the images on the page must be publicly accessible to the Facebook crawler. You should specify absolute url's like http://example.com/yourimage.jpg instead of just /yourimage.jpg.
Can I update these meta tags with client side code like Javascript or jQuery?
No. Much like search engine crawlers, the Facebook scraper does not execute scripts so whatever meta tags are present when the page is downloaded are the meta tags that are used for image selection.
Adding these tags causes my page to no longer validate. How can I fix this?
You can add the necessary Facebook namespaces to your tag and your page should then pass validation:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:og="http://ogp.me/ns#"
xmlns:fb="https://www.facebook.com/2008/fbml">
When you share for Facebook, you have to add in your html into the head section next meta tags:
<meta property="og:title" content="title" />
<meta property="og:description" content="description" />
<meta property="og:image" content="thumbnail_image" />
And that's it!
Add the button as you should according to what FB tells you.
All the info you need is in www.facebook.com/share/
As of 2013, if you're using facebook.com/sharer.php (PHP) you can simply make any button/link like:
<a class="btn" target="_blank" href="http://www.facebook.com/sharer.php?s=100&p[title]=<?php echo urlencode(YOUR_TITLE);?>&p[summary]=<?php echo urlencode(YOUR_PAGE_DESCRIPTION) ?>&p[url]=<?php echo urlencode(YOUR_PAGE_URL); ?>&p[images][0]=<?php echo urlencode(YOUR_LINK_THUMBNAIL); ?>">share on facebook</a>
Link query parameters:
p[title] = Define a page title
p[summary] = An URL description, most likely describing the contents of the page
p[url] = The absolute URL for the page you're sharing
p[images][0] = The URL of the thumbnail image to be used as post thumbnail on facebook
It's plain simple: you do not need any js or other settings. Is just an HTML raw link.
Style the A tag in any way you want to.
From my experience, the http://www.facebook.com/sharer.php does not use meta tags. It uses the string you pass. See below.
http://www.facebook.com/sharer.php?s=100&p[title]=THIS IS MY TITLE&p[summary]=THIS IS MY SUMMARY&p[url]=http://www.MYURL.com&&p[images][0]=http://www.MYURL.com/img/IMAGEADDRESS
The meta tags work with Facebook's developer like/send buttons, as does the other Open Graph info. So if you use one of Facebook's actual elements like the comments and such, that will all tie into the Open Graph stuff.
UPDATE: There are two ways to use the sharer * note the ?s versus the ?u value in the query string
1 ==> STRING: http://www.facebook.com/sharer.php?s + content from above
~~> Will pull info from the string.
2 ==> URL: http://www.facebook.com/sharer.php?u=url where url equals an actual url
~~> Will scrape the page provided in the url value
~~> You can test test the values here: https://developers.facebook.com/tools/debug
Put the following tag in the head:
<link rel="image_src" href="/path/to/your/image"/>
From http://www.facebook.com/share_partners.php
As far as what it chooses as the default in the absence of this tag, I'm not sure.
Old way, no longer works:
<link rel="image_src" href="http://yoururl/yourimage"/>
Reported new way, also does not work:
<meta property="og:image" content="http://yoururl/yourimage"/>
It randomly worked off and on during the first day I implemented it, hasn't worked at all since.
The Facebook linter page, a utility that inspects your page, reports that everything is correct and does display the thumbnail I selected... just that the share.php page itself doesn't seem to be functioning. Has to be a bug over at Facebook, one they apparently don't care to fix as every bug report regarding this issue I've seen in their system all say resolved or fixed.
To change Title, Description and Image, we need to add some meta tags under head tag.
STEP 1 :
Add meta tags under head tag
<html>
<head>
<meta property="og:url" content="http://www.test.com/" />
<meta property="og:image" content="http://www.test.com/img/fb-logo.png" />
<meta property="og:title" content="Prepaid Phone Cards, low rates for International calls with Lucky Prepay" />
<meta property="og:description" content="Cheap prepaid Phone Cards. Low rates for international calls anywhere in the world." />
NEXT STEP :
Click on below link
https://developers.facebook.com/tools/debug
Add your URL in text box (e.g http://www.test.com/) where you mentioned the tags.
Click on DEBUG button.
Its done.
You can verify here https://www.facebook.com/sharer/sharer.php?u=http://www.test.com/
In above url, u = your website link
ENJOY !!!!
For secure HTTPS
<meta property="og:image:secure_url" content="https://image.path.png" />
Use facebook feed dialog instead of share dialog to show custom Images
Example:
https://www.facebook.com/dialog/feed?app_id=1389892087910588
&redirect_uri=https://scotch.io
&link=https://scotch.io
&picture=http://placekitten.com/500/500
&caption=This%20is%20the%20caption
&description=This%20is%20the%20description
I had this problem and fixed it with manuel-84's suggestion. Using a 400x400px image worked great, while my smaller image never showed up in the sharer.
Note that Facebook recommends a minimum 200px square image as the og:image tag: https://developers.facebook.com/docs/opengraph/howtos/maximizing-distribution-media-content/#tags
This is what worked for me: I placed the desired thumbnail image on the page right after the tag and making it too small to see..
<img src="imagename.jpg" width="1" height="1" />
I have not tested it with height 0 and width 0 but it probably will still work.. This does not guarantee the user will select this image..
ALSO it seems like Facebook caches the thumbnails on your page and doesnt always check it for new ones.. try adding this to another page on your site and you'll see that it works.
I couldn't get Facebook to pick the right image from a specific post, so I did what's outlined on this page:
https://webapps.stackexchange.com/questions/18468/adding-meta-tags-to-individual-blogger-posts
In other words, something like this:
<b:if cond='data:blog.url == "http://urlofyourpost.com"'>
<meta content='http://urlofyourimage.png' property='og:image'/>
</b:if>
Basically, you're going to hard code an if statement into your site's HTML to get it to change the meta content for whatever you've changed for that one post. It's a messy solution, but it works.

i had created this web site www.almasryanews.com the problem is when posting a link like this one in facebook (not using the share button in the page) http://www.almasryanews.com/news_details.php?id=217 i don't get the main image but i get some other images from the photo gallery in the sidebar and when using the sharing button in the page it displays the right image though i'm using
<link rel="image_src" href="image path here"/>
how to fix this please ?
you should specify it with adding this to your head tag
<meta property="og:image" content="http://yourwebsite.com/path_to_your_image.jpeg" />
and replace your html tag with
<html xmlns="http://www.w3.org/1999/xhtml" dir="rtl" xmlns:fb="http://ogp.me/ns/fb#">
I suggest you to :
read more about the Open Graph Protocol.
Use the Facebook debugger to know what Facebook actually sees (be aware of caching).
I have tried everything I could before posting this question here on stack overflow.
I am unable to understand why Facebook doesn't pick up any related information to posts on hellyalol for example title, thumbnails or description.
This is an example http://hellyalol.com/181/my-date/
All the open graph tags are in place as shown by source code but facebook debugger doesn't pickup any open graph tag.
<meta property='og:title' content='Will you be my date?'/>
<meta property='og:url' content='http://hellyalol.com/181/my-date/'/>
<meta property='og:site_name' content='Hell Ya LOL'/>
<meta property='og:type' content='article'/>
<meta property='og:image' content='http://hellyalol.com/wp-content/uploads/2011/10/fart-exhibit-150x150.jpg'/>
Another big confusion is When I change permalinks in WordPress for example my-date to your-date it surprisingly works.
e.g http://hellyalol.com/195/years-ago/ this one is working just fine while you share it on facebook but still debugger doesn't pick any open graph tags :S but still I changed the permalink twice for this post before it could work with WordPress
Can any one help? Thanks a lot :(
Server Details: I am using Lightspeed and using w3 total cache with memcache enabled.
Make sure to not miss this in your opening html tag:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:og="http://ogp.me/ns#"
xmlns:fb="https://www.facebook.com/2008/fbml">
This is your current html tag - as you see, some parts are missing (or wrong) there:
<html xmlns="http://www.w3.org/1999/xhtml"
dir="ltr"
lang="en-US"
xml:lang="en-US"
xmlns:og="http://opengraphprotocol.org/schema/">
Just found the answer. For facebook to work with your blog, you should must have www in front of domain. I changed the domain url from http://hellyalol.com to http://www.hellyalol.com and its working
When I link to my website on Facebook a thumbnail comes up but it is not the thumbnail I want to come up. How do I change the thumbnail. It shows the image on the object debugger
http://developers.facebook.com/tools/debug/og/object?q=totelfootball.com
How do I change the image?
I have seen similar posts but want to no a simple solution for the issue? Can it be done on Facebook no coding involved?
you can add into <head></head>
this tag <link rel="image_src" href="http://URL-TO-YOUR-IMAGE" / >
OR change <html> tag to
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:og="http://ogp.me/ns#"
xmlns:fb="http://www.facebook.com/2008/fbml">
and add into tag <head></head>
this tag
<meta property="og:image" content="http://URL-TO-YOUR-IMAGE" />
Don`t forget to test your link using facebook debug tool
Go to http://developers.facebook.com/tools/debug
Enter the URL following by fbrefresh=CAN_BE_ANYTHING
Examples:
http://www.example.com?fbrefresh=CAN_BE_ANYTHING
http://www.example.com?postid=1234&fbrefresh=CAN_BE_ANYTHING
OR visit:
http://developers.facebook.com/tools/debug/og/object?q=http://www.example.com/?p=3568&fbrefresh=89127348912
I was having the same issue last night, and I got this solution from some website.
Facebook saves your cache thumbnail. The thumbnail will not change even if you delete the image from your server. But Facebook allows you to refresh by using fbrefresh
I hope this helps.
You can choose what thumbnail is displayed by adding an og:image meta tag to the HTML of totelfootball.com:
https://developers.facebook.com/docs/opengraph/
Facebook uses meta tags on the page you're sharing to determine which image, title, and description to show when posting a link. The meta tag syntax follows Facebook's OpenGraph specification.
The most important meta tags you need to define are:
<meta property="og:title" content="The title of the sharing preview" />
<meta property="og:description" content="The first few lines of content below the title" />
<meta property="og:image" content="http://example.com/your-image-1200x630px.jpg" />
This of course only works if you have complete control over the site you’re sharing. If you’re sharing an external link (like a news article), you don’t have access to their site and therefore can’t change the meta tags. I'm using ShareKit.io, which allows you to change the title, description, and image of any link you’re sharing without having to fiddle with meta tags.
Easier than this.
Go to the link you shared. Open it in a new tab.
Right upper corner --> Refresh Share Attachment
New thumbnail image gets fetched and you get an option to choose another.
Hope this helps :)
