Why don't attached images show on facebook share?


Well-known member
It's just something bugging me a little and I don't know if it's a facebook thing or a Xenforo thing but why don't the embedded images show on the facebook share/link thingy? Sometimes I want to promote a user's image but all I see is the Xenforo logo.
