^ah sorry, I didn't notice your post until I closed the topic, so re-opened.
Also if you use the code anna provided it could cover up some stuff.

On band profiles the only way to get it under the ad is to do it this way:

If you would like to do that, just put this in either your bio or band members section:
CODE
<div class="one" ><div class="two"><img src="IMG" width="800" height="99" border="0" /></a></div></div>
<style type="text/css">
.one {width: 781px;height: 99px;position: absolute;margin-left: -410px;left: 50%;top: 190px;}
.two {margin: 24px 0px 0px 15px;width: 781px;height: 99px;}
body table { margin-top: 111px;}
body td table, body div table { margin-top: 0px; }
</style>
Please keep in mind when using these codes for band profiles to not say that you just wrote them all yourself

because I do take the time to write these myself.
I suggest not messing with the things for image two, but when editting the positioning use this:
{width: 781px;height: 99px;position: absolute;margin-left: -410px;left: 50%;top: 190px;}
Change the top number to get it write in the space.
and change this to make the space a bit bigger:
body table { margin-top: 111px;}
