[jQuery] Large images IE ready event

In IE 6 through 8, whenever I use $(document).ready(function(){ });,
it doesn't get triggered if there are still images trying to load. I
use a graphic engine to draw huge graphs and it can take up to 5
seconds parsing the images and the code between the ready event doesnt
get triggered until the images are fully loaded.

It works flawlessly in Firefox. Only IE6-8 has this problem. Is there
something I am missing in my code? Is this a known issue with IE?

Thanks.
