you have a point fatman - I agree it could be an 8 year old girl who thought the pictures were great and posted them for others to see. 
I think the solution in this case might be - she delete those images she downloaded from renderosity, ask permission, and repost with credits to the original artists.
Like Aralt3 stated, she doesn't let anyone post her images. I know Rain has sort of gotten the same way since her images have been stolen one to many times on one to many sites lately.
