loadClip in firefox but not IE... please help by testing site :)

Hi Guys
Please could you browse to Legavenue (http://www.legavenue.com/v3/) (NOTE: this is a lingerie site with scantily clad women but no nudity) and try this:
Click on a category like “New Items”
A new page should load, and in the right hand side 14 thumbnails should load.
If they dont load after say 20 seconds, could you let me know? We’re developing the site here in New Zealand, it works fine for us, our client in LA (and San Diego) has mixed results with Firefox and no thumbnails with IE 6. It has us stumped. I’m using loadClip to load the jpegs, and happy to show the code I’m using if needed…

cheers!
