I have operated
http://www.dianajameson.com since 1996. My site has 50,000 pics in the members area with approx 10,000 hardcore and 40,000 softcore pics.
The members area uses copermine database software which monitors every time a picture is viewed. Quess what? In the top 100 most viewed pics only 4 are hardcore!!
You just have to make sure you get the right traffic and have a well designed site with regular updates.
Good Luck!
Diana
