I think you made a wise decision. It isn't morally right to post nude pics of someone without their permission. Not to mention that you can probably depending on where you are at could get into legal trouble. Everyone needs to remember that when you post pics on here they are not secure....I remember reading some posts where people's pics have been stolen and put on other sites. That could be really embarrassing for people's jobs.....political careers.
I don't think a hand in the pic is all that bad......But if there is a chance that someone will beat the shit out of you or get mad.......don't do it!
Ask their permission. Or don't do it at all.
leave it to the Austin girl to set me straight.
