I'm thinking that there would only be a problem if the picture is actually against the code of conduct (ie. nude, or something of the sort that they don't allow). If it isn't she definately won't be punished for it, they might ask you why you reported it and then you can just tell them it was a mistake and sorry.

But if the picture is appropriate (aka nude) I think the FTR community needs to see said picture before we can determine the severity of the problem.
