For my designs, just enter the code into the html section you add to your layout in the page elements section. Use this code below, and then enter the direct link code from under the design you want between the parenthesis:
<style type="text/css">
body {background-image: url("direct link"); background-position: center; background-repeat: no-repeat; background-attachment: fixed; }
</style>
