Scusami un attimo, ma cosa sarebbero tutti quei tag incasinati?
prima <head> poi <html>, ti consiglio di impostare il codice così:
Codice HTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "w w w.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="w w w.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<style type="text/css">
<!--
{border:0px solid #eee;margin:0;padding:0;list-style:none}
html,body,#bg,#bg table,#bg td,#cont{width:100%;height:100%;overflow:hidden}
body{font-family:Arial,Helvetica,sans-serif;font-size:10px;cursor:default;background:url(Abstract_B rush_Wallpaper_by_Tamilia.jpg);color:#000}
img{display:block}
#bg div{position:absolute;width:200%;height:200%;top:-50%;left:-50%}
#bg td{vertical-align:middle;text-align:center}
#bg img{min-height:50%;min-width:50%;margin:0 auto}
body {
margin-left: 0px;
margin-top: 0px;
margin-right: 0px;
margin-bottom: 0px;
}
-->
</style>
</head>
<body>
<div id="bg"><div><table cellpadding="0" cellspacing="0"><tr><td><img alt="" src="http://ourpassion.altervista.org/Abstract_Brush_Wallpaper_by_Tamilia.jpg" /></td></tr></table></div>
</div>
</body>
</html>
