This plug-in is for those who have the problem where sharing a post on Facebook shows the wrong (or no) thumbnail image.

It works by making sure the thumbnail is derived from the featured image of your post. If your post doesn’t have a featured image then it will use a fall-back image that you can specify.

The plug-in inserts the open graph meta properties which Facebook and other social services look for when someone shares your page. These properties contain information such as the title, description (content), and of course the image you specify.

IMPORTANT: End Of Life Notice

Please be advised that this plugin is no longer be maintained. It is recommended you switch to the free (and better) Open Graphite plugin instead, or the Pro version for more options. If you prefer to try something else, no worries, and I sincerely thank you for using this plugin all the same.

If you have any questions about this, I’ll personally respond to any messages sent here. Have fun!

Uninstall

Deactivate the plugin, delete if desired.

How to set a fall-back image

Go to Settings -> General and scroll down until you find ‘Default Facebook Thumb’. Choose or upload a fall-back image. Make sure it’s at least 1200×630 or 600×315.

How to set a Facebook App ID

If you have a Facebook App, you can get the App ID from your developer dashboard.

Specify your Facebook App ID Settings -> General and scroll down until you find ‘Facebook App ID’.

How to set an object type

Posts and pages

On each page or post you edit there is an ‘Open Graph Object Type’ meta box. Simply make a section from there to specify what Object Type the page or post is. Example: If the it’s an article, then choose ‘article’. If it’s a product, choose ‘product’. To help you decide what Object Type to choose, go here to learn the differences between them all.

Note: If no selection is made for posts or pages then the Object Type will be ‘article’, which in most cases is fine.

Home page

To specify what Object Type your homepage is, go to Settings -> General, scroll down until you find ‘Homepage Object Type’ and make a selection. After you’ve specified a Default Facebook Thumb, Homepage Object Type and saved the options, you’ll then be able to view an approximate preview of your homepage when shared on Facebook.

Note: If no selection is made for the home page then the Object Type will default to ‘webpage’, which in most cases is probably what you want.

Known issues

Divi theme is not houring the WordPress strip_shortcodes() function, and so if you have a shortcode early on in a post you may see unexpected results when sharing on social media.
