does any one kno how to have the pic on top of the page where the advertisements go?

Ontop of the ad ?
Or below it?

We will only give you the code for an image below the ad. If you want one to cover the ad you need to find the code at another site. Cb doesn't support ad removal. Plus it can result in profile deletion.

Use this code:

<style type="text/css">body div table td td {height:500px; vertical-align: bottom; background-image:url(IMAGEHERE); background-repeat:no-repeat; background-position: center center;}</style>
