Clothespins on frames. Easy to change out new artwork from the kids. I am pinning this because I really like the caulk board frame, and I love the different sizes and colors, but I think I would go with a cork board back instead of clothes pins.
Fun way to display pictures. This site tells you how they made the wood supports. Then just put picture frames. Easy to change out/add/adjust/etc. I would maybe think about putting some sort of cap on the ends, but love the idea. Adjust to your wall size!
