i only disabled the right click in the home.tpl
handy to stop people from copy and paste your images on home page.
<body oncontextmenu="return false">
...
</body>
or
<script language="javascript">
document.onmousedown=disableclick;
status="Right Click Disabled";
Function disableclick(event)
{
if(event.button==2)
{
alert(status);
return false;
}
}
</script>
