You can just add this to your "head_include" template
Code:
<script language="JavaScript" type="text/javascript">
<!--
function breakout_of_frame()
{
// see http://www.thesitewizard.com/archive/framebreak.shtml
// for an explanation of this script and how to use it on your
// own website
if (top.location != location) {
top.location.href = document.location.href ;
}
}
-->
</script>
and add this to your <body> tag
Code:
onload="breakout_of_frame()"
