A.M.
I'm constantly being tagged in FB photos that I didn't know I was in or that I didn't know would be posted to FB. If you don't want to be tagged, just remove the tag from the photo or don't allow it to be posted to your page.
I don't think it's rude at all. People will always be taking photo's everywhere you go, they don't need your permission to do anything with it. I do think you're over reacting a bit. I don't think she meant any harm.
@Sunnysm0m: for the record I am a very private person. I have a FB account that is so private that people can't even tag me in pictures without my approval first, then once I'm tagged, no one can see them with the tag unless I specifically approve it to be posted to my page. My privacy settings are so high that not even my sisters can post comments to my page, they have to privately message me. I still think this poster is overracting because 1. She could make her privacy settings the same as mine and then her boss would never see it. 2. She was doing something for a "good" cause, she shouldn't be embarrased about it nor should she be upset that someone else was proud about it and took a photo to promote this good cause.
