Depends of what type of ink they were printed with. If the photos were from a photo developer & NOT from your printer, you can usually just run them under cold to barely warm tap water, then set down to dry & don't touch them, but if they are from an inkjet printer that's not an Epson with dura-bright ink, then the ink will run. Take a photo that's from the same batch that you don't care as much about & give the tap water idea a test first. I've done it successfully before.
