I know I've mentioned this before, but since AR 2.5 will be out soon, I know you'll have a lot of free time ;-)
I wish we had a way to view the images posted by a specific user. Let's say you like a picture by RobertSWade or Jacktar51. I'd like to be able to search for their pictures.
Alternative ideas might include the ability to search for threads started by a specific user (right now it is any post), or having the search by user results show that a particular post has a picture attached.
The ability to see just a "gallery" of pictures by a user would still be the best!
