i know how to do a background .. but what is the code for one that doesn't repeat?

you add bg properties="fixed" before you close the tag with >

Last I knew, that only kept it from moving with the page, but it doesn't keep it from repeating. It's best to use CSS for your background image. If you're already using CSS, then put background-repeat:no-repeat; into your body portion of your CSS.

<style type="text/css">
body {background-repeat:no-repeat;}
</style>

Oops, sorry about that, I'm getting my codes mixed up. :D
