[Solved] Why is this background image not showing up?

Hey Guys,

This background image is not showing up on the very top of this page as I'd like it to

Here is the page: http://wisetopic.com/search

The image is here: http://wisetopic.com/_img/_core/bg_top.gif
and is part of the div.wrapper class.

Here is the mockup of how it should look:
http://wisecorp.us/wisetopic/profile/index.htm

in the header body I have added this xhtml:



heres the css:
body {
text-align: center;
min-width: 800px;
margin: 0px;
background: url(http://wisetopic.com/_img/_core/bg_full.gif) top center;
font-family: Arial,Verdana,Tahoma;
}
div, body, p, td, input, select
{
font-family: Arial,Verdana,Tahoma;
font-size: 11px;
}
div.wrapper {
background: url(http://wisetopic.com/_img/_core/bg_top.gif) top center no-repeat;
min-height: 780px;
}
div.central {
width: 780px;
margin: 0 auto;
}

Can you see whats going no, why it is not showing up? Thank you!
