Dynamic jpgs not loading in some browsers

Hey all -

I’ve designed a site that dynamically calls in jpgs into a swf. I’ve done it before on other sites and haven’t had a problem. However on this site (www.jefftse.com), sometimes the jpgs load and sometimes they do not on IE on a mac. Which is bizzare. Why would it not work occasionally?

Has anyone else experienced this problem.

Any thoughts at all would help. Thanks in advance!
