Just stand the binder clip on the flat end and place photos between the arms. Or use two clips on wider images and turn the arms down, balancing the holders on their arms.
You can use this with index cards, memo notes and other small pieces of paper too, as we've mentioned a while back (silly putty to keep the clip in place isn't necessary, I've found, if you have a stable surface).
Your binder clip "photo frame" or note stand takes just an instant to update.
