Photos are free! Even at top level. I have a sim that moved out on her own and her story is that she's broke and trying to make it on the city. But her apartment was pretty sad looking. So she went traveling and took a bunch of landscape photos. I played around with the filters and resized them in bb mode and moved them closer together with moo, and made a pretty nice gallery wall for her. It kind of takes a creative eye to get nice pictures but it's one of my favorite things to do now. Its like custom art! Hope that helps.
