On your social profile (this page where your visitor messages are), there's a box on the right that says albums. There should be a link at the bottom of that that allows you to add an album and you can upload pictures there. After you do that you can add them in a social group or link to them in a thread in the main forums.
I'll review Ozark soon, I'm just catching up on a few I played earlier this month. If you go to the link called "User CP" in the bar at the top of the forum, there are links down the left for adding a profile picture, an avatar and a signature.
