Photo Column

Not sure if this is the correct thread for asking this question, so if not please move.

How difficult would it be to add a photo column to the left side of a post under the following threads. "For Trade/Barter", "Things For Sale" and "Things Wanted" threads??

Example below.

Attachment 8389

It would be nice to see whether or not there is a photo attached to the post instead of opening the post to see. By adding this future you wouldn't waste time opening a post just to find out there is no photo of the item.

Just food for thought.
