I think the charges are ridiculous (sp?). Did somebody force the girl to do this? If yes, charge this person.
This way, the only signal you're sending to every other kid around is: your own naked body is bad! If I remember correctly this is a way of looking at nudity and your own body that was rather popular in the Dark Ages here in Europe...
For me, this is something that should be handled by talking to the parents and teachers of this kid. Maybe even some child psychologist (don't know the exact word) has to sit in there, to make sure that this kid begins to understand what exactly she is doing and why it might not be a good idea to do this stuff.
I'm repeating myself here, but having the family computer in the living room, where the parents are present when their kid is surfing, is imho THE best way to make sure this stuff doesn't happen.
Honestly, I think fourteen is a tad young to begin exposing yourself to the world in such a manner. As much as I enjoy seeing naked women, I think it is fair that those who take photographs of naked men or women under a certain age should be punished. Sometimes I feel that eighteen is a tad too high, but sometimes I feel that sixteen is too low, so I'm not sure which age would be best to be "allowed" to do this at would be.
It does suck that she is being charged for having pictures of herself though...
The discussion about age is one that had, imho no real correct answer. It all depends on the mental maturity of the person in question. And who or what is capable of creating a generic accurate way to define this. I mean, some 15 years ago, most girls aged 16 didn't show much progress in their evolution towards womanhood... nowadays I see 12 year olds with breasts Pamela would be jealous of. So are these girls more mature then the same 12 year olds 15 years ago?
Just my two cents.
