Do you mean on the original site? That site is (for some ungodly reason) written in XML and IE needs different code sent to it (doesn't understand XML). Or, if by IE you meant IE6, position: fixed only works when the image truly is set on the body element (the site has it on a #footer div if I remember right). IE6 needs position: absolute and this will still scroll without some tricks (100% height with rest of page absolutely positioned as well). Should work in IE7.
