I agree with Marc completely... AVS traffic is definitely worth an extra investment in free pics as it converts so well. Most of my experience is in AVS so I have a soft spot in my heart for AVS webmasters.

But as a new paysite owner/operator I also realize that you have to limit your exposure or else you devalue your content.

Striking a fair balance can be difficult especially with smaller pic sets. Andy, maybe you can have your photographer(s) start shooting larger sets with more filler (clothed pics).
