IE not working with site

[Twinky279]

Im about to release my site but i just noticed that while in Internet Explorer do not display the pictures of ads if you want to enlarge them. for example if you go here click on the images to enlarge them, they will not work. But when in FireFox, everything is great. And I know that a majority of the people using internet use Internet Explorer. How might one go about fixing this?

Try
function winimage(fileName,width,height)
{
var domain = location.protocol + '//'+ location.host + '/';
myFloater = window.open(domain+fileName,'myWindow','scrollbars=yes,resizable=yes,status=no,width=' + width + ',height=' + height)
}
