Pagan - you also might check the mouseovers on all of the sites - they all seem to do the same thing
Your gallery2 on the femdom site has a banner going to a billing company that no longer exists - might not make too much cash that way
Also as selling suggestions - its kinda useless to put the pics on html pages unless you put a banner or text link there selling something.
Its also a waste to allow the surfer to go to the "next pic" or "prev pic" as they will just surf the content and leave - make them go back to your gallery page to see the advertising again.
