I am dealing with the same thing right now. It's seems like obvious advice, but don't look at those pictures. I kept looking at pictures and emails, and have driven myself insane. Can't he get rid of those pictures? I don't have pictures of my old boyfriend, and if I do, they are buried in a box somewhere. And if there are kids in the pictures, can't he put up another picture without her in it? Sounds a bit insensitive to me if these pics are just laying around, or even posted online or something.
