Mouseover image not working in IE

[meerimage]

I have a web site that uses this and works fine in every browser. I copied the code but in my new test page it does not work in IE6, still works fine in Firefox. Any help? The test page is at http://www.meerimage.com/test2.htm

Try adding this.

a:hover {
  visibility: visible;
}

I've never messed with the visibility thing, inserting that did not make a difference, but I'll tinker with it a bit and see if I can get it to work that way. Thanks.
