$num_head = rand(1,4);

$stuff = 

"<style type=text/css>

#header a, #header a:link, #header a:active {
display: block;
text-decoration: none;
padding: 0px;
margin: 0px;
width: 765px;
height: 180px;
background: #eee url(http: //www.xxx.com/skins/default/images/header" . $num_head . ".jpg) no-repeat right top;}   

#header a:hover {background-repeat: no-repeat; background-position: right -200px;}
