Testing Facebook Thumbnail

Why does Facebook always use this image for the thumbnail?


This image isn’t the first or the last on the page. It’s not embedded into the post, it’s part of the template. Lately, even when I specify a different thumbnail, Facebook uses this image.

I’m using a plugin called Social, which does a great job grabbing Facebook and Twitter reactions and consolidating them in a blog post. But I’ve spent an hour wrestling with this.
