Trying to hang multiple photos in a perfectly-spaced row or collage layout? Use toothpaste! Place a tiny dab of toothpaste on the back of the photo frame, wherever you want the nail or hook to go. Press the frame against the wall in the desired location. Pull the frame away, leaving the little toothpaste blob behind. Hammer in your nail or hook right in the middle of the toothpaste blob. Your photo will hang exactly where you want it to, without any extra holes or repeat measuring.
