12 meg site optimize options?

Hello my site mcclept.com is heavy on jpegs. I have a preloader that loads the total bytes of entire movie before moving on. This part takes a little too long for me. I know there are better more efficent ways. The jpegs are 72 dpi no bigger than 500 px and publish quality is 65%. Please take a look and let me know if it is not too long or there isn’t much I can do with so many jpgs.

thank you
