What should I do if my boyfriend has pictures of his ex girlfriend on his computer?

Before you opened it, did you bother to check to see the date that file was last opened? Because it's too late now but for all you know it could just be there and he hasn't looked at it in a year. If these were actual snapshots he would probably have them saved in a photo album or box but now they are on his computer. I have boxes full of old snapshots, including pics of ex-bfs in some of them, but I'm not going to throw them all away
