A question about preloaders

i am currently updating my website, www.southpaw.150m.com. the problem that i am running into is that when people first visit my site and click on an icon to see some of my work, they say that the pictures take forever to load. the method that i am using is the load external movieclip via behaviors. all of my works are all saved as .swf and each of them have their own preloaders. what can i do to get my movies to load up faster?
