Or - you make it an acceptably small size and prevent tiling with CSS.
body { background-repeat:no-repeat; }
You can even position it with CSS -
body { background-repeat:no-repeat; background-position:center; }
I am showing the style rule itself. This can be added to your page in three
ways -
1. You can add it to the head of the page in an embedded stylesheet, e.g.,
<head>
....
<style type="text/css">
<!--
body { background-repeat:no-repeat; background-position:center; }
-->
</style>
2. It can be part of an externally linked stylesheet, e.g.,
<link rel="stylesheet" type="text/css" href="foo.css">
3. It can be an inline style on the body tag, e.g.,
<body style="background-repeat:no-repeat; background-position:center;" ...>
FP offers you the way to do #1 and #2 via the user interface, but you would
have to do #3 manually in code view.
