Turn off your cache to see the difference (disable cache from firefox's "Web Developer" plugin).
Basically the only thing I did was set up a wildcard for the subdomains and only put 2 thumbnails per subdomain. It loads 400% faster. Pretty cool trick. Really easy to implement.
The reason it works is because the browser by default only allows 2 connections at once per domain. So I only have 2 thumbs per domain so it can download all the images simultaneously. The alternative is that it has to wait for the previous ones to completely finish before it even requests the file.
As far as the site, it's still in the prototype stage. It's a boob free site I'm working on. Would love feedback. Will add more programs to it, just going through met-art stuff right now mostly. Gonna have a few text links on the bottom. Let me know your ideas for promoting it and how I should go about getting traffic on it. Thinking about skimming off a certain % in trades to other similar traffic sites.
