Sitecheck and loadtime issue

I built:
For a friend. He was ADAMANT about using big, large pictures all over. Being fairly new to flash stuff, I did the best I could. But, when I went to first load the page, it’s preloader took about 2 minutes on a cable modem. Every time I revisit it now, it loads right away. I was hoping someone could check it, see if it loads quickly on another machine or not, and if not, any ideas as to why.
