I print the pictures out myself on photo paper and I use something from Krylon to protect the images. Don't spray it on too thick because it will crack and look bad. A thin coat will work just fine. This one is good for paper. It helps prevent the colors from bleeding. http://www.krylon.com/products/acrylic_crystal_clear
We moved from Germany a year ago and I had something else by Krylon, but we had to get rid of it because they won't ship things like that back. I am almost positive it was this. http://www.joann.com/joann/catalog/p...PRODID=prd2276
I use ET Lite resin for the tops.
