If you "told me" to delete a picture that included you that I had taken in a public place, I would "tell you" no.

If you politely asked, I would generally delete the picture, depending on whether or not there was a reason that I felt I wanted the picture and whether or not there was a way to reproduce the picture without you in it. For example, if Bigfoot had run through the frame while I was taking the picture, I'd be less likely to delete it.

I know only one coworker who understands this concern. No one else seems to care, and the girl I am dating, who is quite technical, has been very suspicious and saddened by me not wanting to put up any pictures of us together. It was basically I relent or something is really wrong, so I gave up. This is the world we live in.
