Strange margin-top between <div>s in IE

[windows]

Hey,
Can anyone explain why this site I'm working on displays the gap between the <div id="head"> and the <div id="content">? It shows about a 5px gap between them in PCIE, but displays fine in Firefox and Safari.

Thanks in advance,
Ian

--EDIT--
I guess a link might help

<!-- m --><a class="postlink" href="http://ten28design.com/WIP/heglerart#head">http://ten28design.com/WIP/heglerart#head</a><!-- m --> img {
display:block;
}Nice!
Thanks BonRouge. So simple!
