Long live Charly
Ok here are my suggestions.
I'd use smaller thumbs on the members page so you can put up more per page like 25.
Sample galleries. Instead of adding one big sample pic and small thumbs I'd generate a centered gallery with small thumbs and making the first 3-4 of them clickable to see the large pics and the gallery could open in a new window.
The search function is not working properly. Let's say I check the filters "solo, glamour, leather/foot" and get no results at all though I have sets from you which fit all of these. You can lose sales on this.
