The user oic in that skin is just a place-holder to keep the alignment of the graphics right. (I think) Most skins don't have a user pic built in with them. The idea was to have a space for the person's regular user pic but many skins have been made with a custom user pic included. If you can view the graphics in the skin's folder, see if the user pic is just a pink square, if it is it's not meant to used.
