Well, the same could happen if instead of nude pics, they were her panties, or a very cheesy love letter, or a webcam striptease, or anything you might call private and part of a love relationship. Does that mean that we have tu punish the girl? Nope. Does that mean we (her parents, school, whatever) have to teach her better? Definitely. Criminalizing (Does that word exist?) something doesn't teach you better.
