IE (9,10) aborts image requests, memory limits?

Hi,

We are working on a prototype that requires loading 100  200px x 2500px images into browser's memory.  So far, we have no problem getting Chrome/Firefox to load all 100 images but IE would abort some of the requests.  If I simply hard code <img /> tags on the page with different URIs to those 100 images, IE would aborts 10-20 of those 100 requests.  If the images are requested via ajax and stored those img reference in a js array, it would roughly fail after 45th image is loaded.  

So, I was wondering if there's any memory limitation with IE 9/10.

Edit: From Fiddler and IE Dev Tool, all those requests completed with 200.  So, it looks like IE made the requests but for some reason, it decided to drop the images.

Thanks,
