XF 2.1 Any way to make og:image the first image in each opening post of a thread?

Right now my forum's logo is showing on Fb when I add a link to a thread, and I wanted to see if anyone knows of a way to make that the first image found in the thread instead? Was discussing this the other day but nothing came of it.

A solution was posted in that thread but, as mentioned, most of the easier methods require guests to be able to view attachments.

@Kevin can you refer the thread? I've lost track of it
