Product Images not showing in IE9

My customer was using 1.3.7 and their server was upgraded to PHP 5.3 which made her site stop working.
So, I upgraded from 1.3.7 to then to 1.3.8 and then 1.5.0. (trying to go from 1.3.7 to 1.5 without doing 1.3.8 didn't work right at all!)

Anyway, since upgrading we have had numerous issues, however the one I cannot seem to resolve is that the product images show when using Google Chrome and Moxilla Firefox but not when using IE9.

The website is: http://photo-calendars.com, it isn't a standard looking site, so click one of the links on the left to go to the product.

Please help.

The product images show up fine for me using IE9; I looked at this page: http://photo-calendars.com/zencart/index.php?main_page=product_info&cPath=0&products_id=39

Really? You see a calendar to the right of the description and right below the price of the calendar?

Yep, IE9 v9.0.8112.16421 on Windows 7 Home Premium SP1 64-bit.

There's a calendar with a picture of a woman and 2 children for January 2007.

Thank you! I hate this computer. It's my daughters because mine crashed, but it has never worked right. I truly appreciate the help!!
