Hi Mike,
I also have an issue in IE7 & 8. When you click into a category and then go onto the 2nd page the images aren't showing. I've tried your solution above but unfortunately it isn't working. Any other ideas? The site is working perfectly in firefox, chrome etc.

For example, click into the mens category, scroll down and click into the 2nd page of products and the images aren't there. When you then click back to the 1st page the images have also disappeared, although they are there the 1st time you view the page.
Thanks for your help,
