You have a ratio of 1:599, which is not that bad considering Met-Art is oversaturated. But a few sales and few outgoing clicks do not tell anything (it could as well be 0) and with 150,000 visitors to gallery you need to work on the design. Your lack of links (especially at top) makes the impulsive surfer think "how do I get to the paysite?". I bet Met-Art had type-in sales, because YOU didn't provide sufficient affiliate links.
Instead of one banner at bottom only, use text link and a description of the site (like: met-art updates daily etc). Because if you didn't convince the surfer with the pictures, and their eyes got as far as to the bottom of page, then it's your job to convince them with text.
The optimal design is to fit everything into a non-scroll page, so work on the thumb sizes and table width. Get rid of the counters, you do not want surfers to click those buttons (isn't your server logging the traffic?). Also place referal code in front of your 2257 link (...&HTML=..)
The Hun prefers clean galleries, but that doesn't mean it should looks so 90's. The HR lines screams too much and is only waste of space.
The Hun is also better for fetish and hardcore, not so much the glamour stuff.
