Background Url, -help- Options

[YourSuperior]

How do I get a url for a background or a banner to look like this:

CODE

<style type="text/css">
body {
background-image: url("images/Adriana_Lima_Pics/blend1.png");
background-repeat:repeat-x-y;
background-position:top left;
font-family: Franklin Gothic Medium;
font-size: 14pt;
text-align:left;
}
</style>
