Post your pictures only in place where only your friends can see them or don't post them at all - ask yourself if you need to even post them in the first place. Maybe choose to show your photos to your friends during meetings instead. The only way for a photo to not be usable by some future AI is to turn it into random noise which defeats the purpose of posting it.

Paranoia speedrun 101. A creep will get your photo anyways. Projecting your fears on random men will only be detrimental to your mental health and social relations.
