That gallery really sucks I gotta say.
Content doesn't match the site you want to sell.
Crack addict cheerleaders might be a better site for that content
Say you got 150K uniques.
I bet that gallery didn't do better then 0.5% ctr but lets say it does 1%.
So that's 1500 clicks.
1:1500 isn't good but i've seen worse.
Try a new gallery layout and make sure your content matches the site that you want to sell.
