AIBU Picture of me shared online

I can't decide if I'm being unreasonable or not.

About a month ago one of my housemates was over, unbeknownst to me. First I knew was when I went to take a shower and she surprised me by being in the hallway with her phone out taking pictures. Apparently she'd been snapping other housemates too, as well as the other people who were over. At the time I laughed it off.

Just before Christmas it turns out she's been sharing the pictures of me (I don't think the others) on her socials. Now I feel it's a bit intrusive and asked her not to. She told me to lighten up, get over myself etc.

So am I being unreasonable insisting? After all I laughed it off at the time, and I'm not hyper-shy about people seeing me just in a towel - like if we just happened to be at the gym or beach or whatever. It's not so much the pictures themselves, if that makes sense, but the way they happened.
