Hi Daryl,
The source code shows the images code as having no given widths or heights, which is why I guess IE is not displaying them.
I don't know how the code is generated (dynamically?) or if it is as it appears, but it manifests as:
<li class="show"><img src="images/aurora_web.png" width="" height="" alt="pic1" /></li>
<li><img src="images/Gotica_page_copy.png" width="" height="" alt="pic2" /></li>
<li><img src="images/ouvo_pb_web.png" width="" height="" alt="pic3" /></li>
Are you able to add the image widths and heights to your page code? This would allow them to show up in IE.
