x i POPUP Automatici io uso questa funzione:

<html>
<head>
</head>
<script>
function dimensiona()
{
var a = document.foto.width;
var b = document.foto.height;
var larg = a+10;
var altez = b+50;
window.resizeTo(larg,altez);
}

function prendiescrivi()
{
var passed = location.search ? unescape(location.search.substring(1)) + '&' : '';
var imageSrc = passed ? passed.substring(0,passed.indexOf('&')) : 'px.gif';
passed = passed.substring(passed.indexOf('&')+1);
document.write('[img]' + imageSrc + '[/img]');
}
/*,screenX=200,screenY=100,top=100,left=200*/
</script>
<body onLoad="dimensiona(); self.focus()">
<script> prendiescrivi();</script>
</body>
</html>
