To the best of my knowledge there are NO nude pics. There are a few 'slips' (not very good ones nor very many either) and a few wet-T sets. The only time I've even heard of actual nudes though is when people ask if there are any, and I've always heard that question answered with 'no'.
I'd like you to prove me wrong (one of the few times I'd LIKE to be wrong), but I don't think you will.
