The squares are a really good solution if you have to take care of a lot of pictures and for a cheap way) I bring home around a average of 1200 pic from vacation and I do not believe in, of having everything only on the computer, so I print them out. I need a average of two squares for one pic. It's very easy to handle and most importand i can take care fast of it. If you have the photo-corners it takes a lot of time to get them in and their also come easy out and you need 4 of them. So I think the squares are the best solution.
