Thumb Fixer for Social Media

IMPORTANT: This plugin is no longer being maintained. 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.

Install, activate, done.
