Featured images in WordPress

The “featured image” that you can set in a WordPress post is a purely internal thing. Some themes use it, some don’t, and how they use it depends on the theme. Adventure Journal for example, the theme I’m now using on this blog, uses a featured image of the correct size as a custom header for the post. So far, I’ve made use of this here and here.

But if, for example, your posts are published automatically on Facebook, the featured image will not necessarily be chosen as thumbnail. So, if your theme isn’t using it, it’s pointless to set one at all, and it’s better not to. If you ever change your theme to one that does, you might not like the way it uses the featured image at all.
