CSS Code for background

Can someone edit the background picture of [url=gtamf.forumotion.com/forum]this[/url] forum

Code:

html {
background: #000 url("(http://i.imgur.com/PP8b8oi.png") repeat;
/* Height is 100%, so the body can be 100% */
height: 100%;
background-attachment:fixed;
background-position:center center;
}

body {
background: url("") no-repeat;
background-position: bottom center;
/* Height is 100%, so the tiled BG will tile all the way down
 the page, not just as far down as the page’s content
 (when the content’s height is less than the window’s height) */
}

html>body {
 min-height: 100%;
 width: auto;
}


 body {cursor: url(http://www.myspacecursor.net/cursors/3.cur); }
