Perhaps not exactly what you were looking for, but if you use clickcash (see my sig) you can specify a link to their 'legs' catagory. On one of my sites I wrote a script that extracts images directly off the ifriends site, and uses them to produce constantly changing banners, and a half-page console.
It does well, considering the small amount of traffic the site gets. Something to think about

ClickCash - Better than 1:99 and $50 for signing up
Lightspeed Cash - Converts like crazy
