There are other problems with the layout (possibly also caused by this same thing) but, the thing that is preventing it from showing up at all in IE are the non-standard HTML comments, ex:
Code:
<!--********************************************* CAVALIER WHITE PATTERN START --***************************************>
A comment should begin with:
<!--
and a space.
A comment should end with a space and:
-->
There were several of these non-standard comments in the portion of the markup that contains the images for the gallery. IE thinks that the code for the images is a part of the comment(s) and not to be displayed. The above example comment could be made standard like so:
Code:
<!-- _______ CAVALIER WHITE PATTERN START _______ -->
