[The D]

Hello everyone!

If this has been requested before, I apologize, but I've found no answer.

Basically, I'd like my users to be able to upload an image (or use the first attachment in their post, for example) to be placed on the view forum section. If I'm not making any sense, I basically mean like here:

According to their system, it takes the first thumbnail that a user posts and uses it.

I'd really appreciate anyone's help on how I could do this.

Thanks so much!

EDIT:: I saw that someone was requesting a custom post icon, and while I think my request is still a little different (considering I'd be happy with the first attachment thumbnail), I apologize if this would be considered a duplicate thread.
