Ie9 - Image sizing error in product page

Hi,

The problem appears only the first time the page is loaded on my end. The second time the image is find.
It seems that there is something on your template which preloads the images on the page and which apparently causes the problem. Also, I see that you edited the file show of the view product and removed the modal popup on the image, and maybe added the height and width in the image tag ? It's hard to tell if it comes from a modification of the view or the template. But that doesn't seems to be a problem in HikaShop itself.
Maybe you could start by switching your template to see if you still have the problem or not. If yes, you should ask your template provider for help.
