    <html>
<script type="text/javascript">
function autoIframe(frameId){
try{
frame = document.getElementById(frameId);
innerDoc = (frame.contentDocument) ? frame.contentDocument : frame.contentWindow.document;
objToResize = (frame.style) ? frame.style : frame;
objToResize.height = innerDoc.body.scrollHeight + 10;
}
catch(err){
window.status = err.message;
}
}
</script>



<iframe id="tree" name="tree" src="tree.htm" onload="if (window.parent && window.parent.autoIframe) {window.parent.autoIframe('tree');}"></iframe>

    thats a script i had saved in my temlates, it isnt mine though! but i cant remember who was author..

    doing a search on google returned:

    <script language="JavaScript">

function calcHeight()
{
  //find the height of the internal page
  var the_height=
    document.getElementById('the_iframe').contentWindow.
      document.body.scrollHeight;

  //change the height of the iframe
  document.getElementById('the_iframe').height=
      the_height;
    }
<iframe name="the_iframe" onLoad="calcHeight();" scrolling="no" width="730"  id="the_iframe" src="you_page.html" frameborder="0" allowtransparency="true"></iframe>
