Hi !

In order to pass the screens height and width via hidden form parameters, you could insert something like this into your html:

<script TYPE="text/javascript" LANGUAGE="JavaScript">
function fill_in_screensize() {
  document.forms['main_form'].width.value=screen.width;
  document.forms['main_form'].height.value=screen.height;
  return true;
}
</script>
....
....
<form name=main_form>
<input type=hidden name=width>
<input type=hidden name=height>
<input type=submit onClick='fill_in_screensize();'>
</form>

I don't know much javascript myself, so please don't rely on the code working on all browsers.
