Para terminar voy a poner el script original y la modificación necesaria para que funcione...
<head>
<script>
function copyrightIntro(url)
{
if (!document.layers&&!document.all&&!document.getEle mentById)
{
paramstp=" height=400,width=400,top=0,left=0,scrollbars=yes,l
ocation=no"+
" ,directories=no,status=no,menubar=no,toolbar=no,re
sizable=yes"
//var crw=window.open(
url ,"",paramstp);
var crw=window.open(
"" , "", paramstp);
var interior = "<html><body style='background-image:url(" + url;
interior += ");background-color:" + "red" ;
interior += ";background-atachment:fixed;background-position:center center;background-repeat:no-repeat";
interior += "'></body></html>";
crw.document.write(interior);
if (crw.focus){crw.focus();}
return;
}
var winwidth=200;
var winheight=50;
var winreswidth=window.screen.availWidth;
var winresheight=window.screen.availHeight;
var LeftPosition=(winreswidth-winwidth)/2;
var TopPosition=winresheight-winheight/2;
var paramstr="left="+LeftPosition+",top="+TopPosition+ ",width="+winwidth+
",height="+winheight+",toolbar=no,menubar=no,locat ion=no,"+
"status=no,scrollbars=yes,resizable=yes";
var crw=open(url,"",paramstr);
crw.resizeBy(0,-40);
var resspeed=100;
var wspeed=winreswidth/resspeed;
var hspeed=winresheight/resspeed;
var x=wspeed;
while (x)
{
crw.resizeBy(x,0);
winwidth+=x;
LeftPosition=(winreswidth-winwidth)/2;
TopPosition-=wspeed;
if (LeftPosition<0) LeftPosition=0;
if (TopPosition<0) TopPosition=0;
crw.moveTo(LeftPosition,TopPosition);
if (winwidth>=winreswidth) x=0;
}
crw.moveTo(0,0);
var y=hspeed;
winheight=50;
while(y)
{
crw.resizeBy(0,y);
winheight+=y;
if (winheight>=winresheight) y=0;
}
crw.resizeTo(winreswidth,winresheight);
if (crw.focus){crw.focus();}
}
</script>
</head>
Espero que te sirva...
