grazie per avermi risposto.No purtroppo non rientro in quella casistica in pratica, richiamo i file.js cosi:

codice:
<head>
<title>Esempio</title>
<script type="text/javascript" src="js/script.js"></script>
	
	<script>
		if(t_pixel=="1024 x 768"){
			document.write("<style>body{font-family : arial,sans-serif;font-size : 12px;text-align : center;background-image:url(img/SF_1024X768.jpg);}</style>");
		}
		else if(t_pixel=="1440 x 900"){
			document.write("<style>body{font-family : arial,sans-serif;font-size : 12px;text-align : center;background-image:url(img/SF_1440X900.jpg);}</style>");
		}
		else {
			document.write("<style>body{font-family : arial,sans-serif;font-size : 12px;text-align : center;background-image:url(img/SF_1280X1024.jpg);}</style>");
		}
	</script>
<script type="text/javascript" src="ruzeeborders/ruzeeborders.js"></script>
<script type="text/javascript" src="gallery_home/image-slideshow.js"></script>
</head>

<body class="fontA" bgcolor="#000">
forse faccio un'errore qui?
Bo, dimmi te...
