Background Image not shown
Your css is the problem.   There is no images/bg.gif.  There is an image/bg.png file.

Change

body {
    background: url("images/bg.gif") repeat scroll 0 0 transparent;
    color: #666666;
    font-family: Tahoma;
    font-size: 12px;
    padding: 0;
    text-align: center;
}


to:

body {
    background: url("images/bg.png") repeat scroll 0 0 transparent;
    color: #666666;
    font-family: Tahoma;
    font-size: 12px;
    padding: 0;
    text-align: center;
}
