Um, okay, I don't mean any offense in saying this, but please remember that I'm the Admin here and currently the one in charge. I don't need to be told how to handle a situation that I've dealt with several times. Also, I know this user pretty well and I know she usually would never cause a problem, so I don't think it'd even be necessary.
Also, uh, are you sure it's fanart? We allowed it back when it was originally uploaded because it looked official. There's text on the upper corner as well that also looks official to other images we have.
