This code is for a popup that will display a screenshot. I would like the user to be able to resize the window, but not have the window wider or longer than the picture.

However, I do not know how to capture the .onResize so that the script executes...

window.onResize="resizeme()"

Code:
<script type="text/javascript">
<!--
function resizeme() {
var mywin
if ($pic_sizex == self.width && $pic_sizey == self.height)
{
window.resizeto("$pic_sizex*$factor, $pic_sizey*$factor")
}

else if ($pic_sizex*$factor > self.width)
{
window.resizeto = ("window.width, $pic_sizey*$factor")
}
else ($pic_sizey*$factor > self.height)
{
window.resizeto = ("$pic_sizex*$factor, window.height")
}
}
// -->
</script>
thanks again for your help, it is always appreciated,
