Like Thumbnail Plugin

Plugin for specifying which thumbnail to use for links liked/shared on Facebook.

Archive page

Get a media attached to the first post it can find

Singular page

• Use featured thumbnail when available
• Use one of the media attached, when available
• Fallbacks to the default image (like a logo which can be specified in settings)

Filters are available if you want to shortcircuit the logic or want to add yours.

It just works! If it doesn’t work for you, let me know by creating an issue here – https://github.com/ashfame/facebook-like-thumbnail/issues

• Upload the folder facebook-like-thumbnail to the /wp-content/plugins/ directory
• Activate the plugin through the ‘Plugins’ menu in WordPress
• Settings are in Setting > Facebook Like Thumbnail

How do I change the default image to be used?

Go to Settings > Facebook Like Thumbnail and enter URL to the default image you would like to use

When is the default image used?

When plugin can’t figure out the image to use in any context, then it will use the default image.

Is it possible to add my own logic or shortcircuit existing logic?

Yes! Take a look at plugin’s source code, pretty easy to hack away! 🙂

Why does it still show an incorrect thumbnail?

Facebook will update it for all the pages within 24hrs. If you want to refresh for a particular page manually, then you can use the Linter tool – https://developers.facebook.com/tools/lint/
