I'd say that the pics being out of order is the most obvious problem. She's naked, she's dressed, she's naked, she's half dressed, she's naked, etc. Greeny spits out a big mouthful of Redbull whenever he sees that kind of thing.
I looked at one pic that was 240kb. We like to see those sizes down to a max of 80kb or so.
From a selling standpoint, I'd personally place more ads. We still allow 3 per page, so you might as well use them. I'd definately put one below the enter/exit links on the index.
