How do I change the size of my myspace background without tiling it?

I want my picture to cover the whole profile without having it tile. I tried to resize it using css, but it wouldn't work. Here's the code that I'm trying to use:



%26lt;style type=';text/css';%26gt;



body{background-image:url(';http://i179鈥?br>
background-attachment:fixed;

background-repeat:no-repeat;

background-position:center;

background-color:000000;

scrollbar-face-color: aa0000;

scrollbar-highlight-color: 000000;

scrollbar-3dlight-color: aa0000;

scrollbar-shadow-color: 000000;

scrollbar-darkshadow-color: aa0000;

scrollbar-arrow-color: 000000;

scrollbar-track-color: 000000;}



table, tr, td{background-color:transparent;

border:transparent;}



%26lt;/style%26gt;
