When I click the share button for one of my wordpress posts, a popup window successfully opens. It displays the correct thumbnail image, and the title and summary text are correct as well.
However, when I actually go and look at the share on facebook, the thumbnail is not correct. For some reason facebook always shows the thumbnail for the first share I ever made for every single share I make.
What's weird is the title and summary are always correct, but I just can't get the thumbnail to work properly.
Here is the code I use for my Facebook share buttons:
<a class="facebook" onclick="return !window.open(this.href, 'Facebook', 'width=640,height=300')" href="http://www.facebook.com/sharer.php?s=100&p[title]=This Is The Title Of My Post&p[summary]=This is the summary of my post.&p[url]=http://www.mywebsite.com/individual-wordpress-post/&p[images[0]=http://www.mywebsite.com/images/this-is-my-thumbnail-image.jpg" target="_blank"><img class="size-full wp-image-96 alignleft" alt="shareonfacebook" src="http://www.mywebsite.com/images/this-is-my-facebook-share-button-image.jpg" /></a>
I put this code together after reading the following answers here.
Any ideas why the title and summary are always correct, but the thumbnail is never right? Remember, when I click the share button, the thumbnail is correct in the popup window but not the same when I go and look at the share on facebook.
Thanks for the help I really appreciate it.
Facebook uses the Open Graph protocol to determine what information is displayed when sharing a web page. The problem is more than likely not with your link but with missing Open Graph tags.
To debug the problem, copy/paste the URL you're testing into the Facebook Open Graph Debugger and press the 'Debug' button. The debugger will display the information Faceebook will use when sharing that specific URL.
As an example, the Open Graph tags for the home page of Stackoverflow are:
<meta name="og:type" content="website" />
<meta name="og:image" content="http://cdn.sstatic.net/stackoverflow/img/apple-touch-icon#2.png?v=fde65a5a78c6"/>
<meta name="og:title" content="Stack Overflow" />
<meta name="og:description" content="Q&A for professional and enthusiast programmers" />
<meta name="og:url" content="http://stackoverflow.com/"/>
The output for the Open Graph debugger is shown below.
To resolve your problem, you can:
Change your Wordpress theme to output the Open Graph tags on each post/page.
Install a plugin to output the Open Graph tags. Facebook have an official plugin or you can use Wordpress for SEO which will output Open Graph tags and also meta-data tags for Twitter.
To solve this problem you need just to edit your theme header.php and set this code below the tag:
<?php
if ( has_post_thumbnail())
{
$fb_image = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'full');
}
?>
<meta property="og:image" content="<?php echo $fb_image[0];?>" />

Our support pages contains link to our videos on youtube with additional instructions. I've a requirement that when a link to our support pages are shared, the thumbnail should be displayed. i.e., link is to our website, but the thumbnail should be from our youtube video. The share can happen on social sites or email, etc. I've tried sending sharable link and something like below, but it does not work:
<img src="https://i.ytimg.com/vi/f3Synm4U4Uk/hqdefault.jpg"">
How does youtube do that? When you share their sharable link, the thumbnail and video button shows up. It is almost like the receiver(WhatsApp/telegram/etc) sends a get request to youtube to get the thumbnail upon receiving the YouTube link and display that.
You can't always control how a third-party client displays a link to your website, but a standard way of doing this is via the Open Graph protocol. This allows your website to contain metadata that robots can use to categorize your website and add metadata to links.
To tell a robot which image to show with your link, you can use the og:image tag, like so:
<meta property="og:image" content="https://c7.uihere.com/files/293/500/890/adorable-animal-cat-cute-thumb.jpg" />
Along with the thumnail you can add a lot of other metadata, such as a title and a description:
<meta property="og:title" content="Your link title" />
<meta property="og:description" content="Some description of your webpage" />
I'm attempting to set a custom thumbnail for when people share my website on Facebook. I followed this post here: How does Facebook Sharer select Images and other metadata when sharing my URL?
It seems this info may be outdated because I am unable to get it to work. Can anyone advise if there has been a change and how to handle this now?
I currently have this in my head but It is not working:
<head>
<meta property="og:image" content="http://placehold.it/350x150"/>
<meta property="og:image:secure_url" content="https://placehold.it/350x150" />
</head>
Figured it out. Facebook simply had not refreshed my images yet. I found this tool to help with this process:
https://developers.facebook.com/tools/debug/
In some websites like facebook, when we post some link it show us thumbnails from that website, Like this in Picture below:
How to do that?
you need to fetch that URL and read the meta tags which will give you some information such as title, description etc. If you need to fetch the image weather read the image meta tag (exists if any) or read the first available image from the web page.
It's just a post/comment like any other. Only thing you need is info about that page. You can use curl for example to fetch page's data. Info you are looking for are in head of document in meta tags.
<meta name="og:type" content="website" />
<meta name="og:image" content="http://cdn.sstatic.net/stackoverflow/img/apple-touch-icon#2.png?v=fde65a5a78c6"/>
<meta name="og:title" content="Post a link and show thumbails from that link - php" />
<meta name="og:description" content="In some websites like facebook, when we post some link it show us thumbnails from that website, Like this in Picture below: How to do that?" />
Take those info and make your post/comment/whatever.
EDIT:
You don`t even need curl, you can use file_get_contents check out this answer
I'm working on a not for profit website, and trying to integrate with facebook. The app seems to work fine, single sign on works fine, even a custom "post to wall" function works fine using the javascript sdk. What does not work, however, is adding a photo to represent the entity, and anything other than default text, when a person clicks on the like button.
What's worse is there is some ghost text that I personally have never actually seen (other than in the text box itself) that finds its way into the dialog box when posting and leaving the text box empty.
The documentation here falls short:
https://developers.facebook.com/docs/reference/plugins/like/
Open Graph API tags also did nothing.
If you "like" the "like button" you'll see that their example does exactly what I'm trying to accomplish. There's a photo and a little description of what the button is. Is it possible to do this on other sites?
I've struggled a lot with this myself, but I found that by putting my page's URL into Facebook's debugger, it made the correct image, text, etc. show up when clicking a share button.
Add these tags in your pages' tags.
<html xmlns:og="http://ogp.me/ns#">
<head>
<meta property="og:title" content="insert your title here"/>
<meta property="og:type" content="website"/>
<meta property="og:url" content="http://www.example.com/foo/"/>
<meta property="og:image" content="http://www.example.com/images/example.jpg"/>
<meta property="og:site_name" content="A human-readable name for your site">
<meta property="og:description" content="A one to two sentence description of your page">
</head>
</html>
To turn your web pages into graph objects, you'll need to add Open Graph protocol tags and the Like button to your webpages.
Instructions are here:
http://developers.facebook.com/docs/opengraph/
Trying to implement the example from here.
Facebook Share passes along the URL of
your page to our servers, which in
turn looks up certain HTML tags within
it. Those tags are used to display a
preview of the page. In order to
provide this preview, we always look
for the title of the page, a summary
of the main content and an image.
http://developers.facebook.com/docs/share
I added the share button to my site as described on the share page linked above.
<a name="fb_share"></a>
<script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share"
type="text/javascript">
In the header I added the tags it requires to create the preview in the news feed.
(I used the example tags, just to see if it would work.)
<meta property="og:title" content="Smith hails 'unique' Wable legacy" />
<meta property="og:description" content="John Smith claims beautiful football
is the main legacy of Akhil Wable's decade at the club. " />
<meta property="og:image" content="http://www.onjd.com/design05/images/PH2/WableAFC205.jpg" />
</script>
When the shared button is clicked it takes me to small shared window and I hit share.
However, when I navigate to my news feed, no preview of the page shows and none of the header tag information. It just shows:
Greg McNulty http://localhost:2259/iState/Shared.aspx?id=a051fc1b-4f51-485b-a07d-0f378528974e localhost 7 minutes ago · LikeUnlike · Comment · Share
Why isn't the preview working? (I get this same result without the header tags.)
Thank You.
(FYI - I am using the share because it allows for multiple shares of the same page whenever needed, compared to the like that allows it once and then the button physically changes saying the page is already liked.)
You can test how Facebook servers see your webpage by feeding the URL to this service.
http://developers.facebook.com/tools/lint/
In order for OpenGraph to work a facebook server must be able to visit the URL without a session or cookie. This means "localhost" web pages cannot pass open graph data.
