When I send a post to facebook, doesn't matter if I use the Share Button or just copy and paste the article url, images are randomly loaded. I mean that if the articole has an image in it (not necessarily marked as "featured") sometimes it loads as thumbnail on facebook, sometimes it doesn't.
If I click on the like button within sharebar it usually works and the image is correctly posted on facebook side by side with the article.
Is there a fix to it? Thanks!
