Pics of ex found

Its a new relationship (3months) and she asked me to move files from an old pc, whilst moving them I was checking folders were empty.........I came across a folder with a few pics of her and her ex having sex from 3/4 years ago.....and if Im honest its on my mind......do I say something to get it off my mind or try to deal with it on the basis that it was her ex, it was years ago and her past which was nothing to do with me?

Dear, I think that person is would not be loyal for you. because who can save the pic like this private time spent with his girlfriend. he can do same with you. So what do u do. It may be create a big seen with you and you privacy so be careful.
