Nice first site!!!
These guys have made some really good, constructive comments. The alt tag is vital, and you really should use it with every image. You can use a tag line, like "InFocusGals Mean Real Teens, Real Action, Real Orgasms" so that people who have to wait for images to load have something to entertain themselves with. Yeah, there are other reasons but do they really matter?
With the content, your sponsor really does have quite a bit (I use them too). You will easily find great sets that you can cull out of the 18s. Do 2 sets of 12 and you will fit most of the LLs out there. If you really feel wild, do 2 15s. Persian Kitty really only takes 30 pic sites. I know those are placeholders.
Also, learn to add titles to all of your links. That's what you see when your mouse crosses over the link. A little entertainment value, more food for search engines, etc. These are really minor things that come along with HTML. Even when I do a gallery link, it is <a title="Hot Model Tease Gallery 1" href="gallery1.html"> so that the surfer gets a little thrill.
Pretty site... you have a nice clean style. I would certainly list you.
