Is it acceptable to have photos of your exes (kissing, nude etc.) on display all of the time?

He has a projector screen and an Apple TV instead of a regular TV, when the Apple TV idles it shows pictures that are on the Apple TV. A majority of these pictures are of the exes, some are of them kissing, groping, naked etc. I don't want to see that, more importantly, if anyone else is here I don't want them to see that. Again, it just feels disrespectful.
