Mom keeps taking pictures of me and posting them online

Mom keeps taking pictures of me even though I hate having my picture taken and have expressed this to her many times

she posts them on Instagram and Facebook and these posts are PUBLIC so everyone can see them it really stressed me out and makes me feel embarrassed I have a lot of insecurities about my body and face; Once she posted videos of me in my swim suit something I told her explicitly not to do I was really upset and felt sick seeing the picture as I have some issues with body dysmorphia, she did eventually take it down only after I got really upset.

There are some others that I have asked her to take down but she always refuses saying stuff like "I'm the one preserving the memories you'll regret saying this after I'm gone" or something to that affect, okay fine but do you have to post them online?!!!, or "oh but only friends and family see them" NO they are public mother, I don't know what to do I have mentioned this to her several times, I love my mom but this really gets under my skin and can't seem to get her to understand.

Anyway rant over does anyone have any advice?
