Is it inappropriate or weird to send things back to an ex years later?

So, we’re moving and I have to go through soo many old boxes. I found a lot of stuff from exes. I’m totally a packrat, so this stuff has been in my parents attic for years.
I found pictures, and really don’t want to keep them. But, I don’t want to throw them out because I’m weird like that.
I asked my husband if it was weird if I just mailed them back..he said that’d be really weird. I don’t see why though. I like having pictures to remind me of memories or see how ridiculous I looked back in high school. So, what should be done with these photos?
