One day, I was bored, and I went and walked around World Showcase and my goal was to take one interesting shot at each pavilion. I ended up with a bunch of cool "artsy" shots that I wouldn't normally take. The details that Disney puts into their architecture are so beautiful that it's not hard to find pretty shots if you're looking for them.
Also, for fun pictures with people in them, I highly recommend posing with statues and mimicking the statues. It sounds lame, but it's pretty much our favorite Disney activity now that we've ridden everything a hundred times. Best photo op: the Buzz Lightyear statue outside of Once Upon a Toy at DTD. His right arm is positioned just perfectly so that if an average height female puts her arm around his shoulder and stands on that side, it looks like he's grabbing her butt. We didn't even notice it until we downloaded our pictures the first time, but now it's our absolute favorite. We now plan DTD trips just to take our picture with our favorite statue, who we have a special nickname for that can't be shared on these boards. :goodnevil
