My friends take photos of me without my permission and send them to people

My friends take photos of me and they send them to gc with other people. One is creepy asf. He asks for photos of me and sends them to gc’s. He randomly dm’s photos of me to people(i’ve been told by some other friends) they wont delete them if i ask too. The photos aren’t revealing or anything, they’re just embaressing where i look ugly or so goofy looking. These guys dont stop. I stopped hanging out with them so they have less fuel but i want the photos of me off their camera rolls.it’d be fine if tjey send it only to ppl i’m chill with but they send them behind my backs. I have embarrassing photos of them(i don’t like sendint them anywhere) so whenever i tell them to delete them they say”you have photos of us stop being a hypocrite”
