I love the new social and Open Graph features with the latest update and it's actually cured almost all the problems I was having with Facebook except one—the og:image tag is missing for my webcomic pages. I imagine this is because my webcomic plugin uses custom post types, but a few months ago, Facebook was able to consistently find the images.
Is there a way for WordPress SEO to automatically populate that tag for the custom post types of my webcomic pages? The way my plugin works doesn't use the standard WordPress uploader so I can't simply select the images as a Featured Image—they don't live in the gallery.
This is the URL I'm testing through their linter tool:
Maybe this problem won't have an easy solution. But if there's anyway to help me get my comic page images back into FB posts, that would be awesome.
