fb link thumbnail If you use Facebook, you know that when you share a link, it will try to find an image on the page and create a thumbnail.  If you use Facebook to promote your website, you have probably been frustrated more than once about how Facebook chooses what images it uses.  Here are a few quick tips to help you out.

  • Image Size: Facebook requires that any image it uses for a thumbnail be at least 200px by 200px.  Make sure your image is this size or bigger.
  • WordPress Featured Images: I recently found this plugin that will add the right code to featured images so Facebook will use them for thumbnails: Facebook Featured Image and Open Graph Meta Tags.  I haven’t used this plugin myself, but it looks promising as it has great reviews and claims a very easy “install it and forget it” usability.
  • No Image Found: For those using WordPress, the plugin WordPress SEO by Yoast has a feature where you can set a fallback image for your site if Facebook doesn’t find any images.  Chances are you already have this plugin installed, but if you don’t you should.
  • debugger tool Clearing Facebook’s Cache: After you’ve done all you can to change the image, Facebook may still have old image thumbnails cached for your link.  To make Facebook change the image, go to Facebook’s Developer Debugger Tool.  If you don’t consider yourself a “developer”, don’t let this scare you.  All you need to do is go the page, paste in the URL, click “Debug”, and Facebook will re-gather all of the information for the link and set that to it’s cached version of the link.
  • Other Issues: The link mentioned above, Facebook’s Developer Debugger Tool, can help you figure out what else is going on with your link, not just images.
