I'm having trouble, can someone help?, changing an exisiting layout image Options

[hailyuhhhxx]

I found an overlay layout that I really like, but it's a christmas one. I want to change it so that I can make it for now, since Christmas is over. I figured out the majority of it, but I can't figure out how to change the large picture at the top. The code for the picture at the top looks like this :

<div class="back"><img src="http://cbimg6.com/layouts/07/12/20/23891ac.png" width="800" height="738" border="0" alt="" usemap="#santababylayout_Map">
<map name="santababylayout_Map">

When I try putting a new URL in the picture just doesn't show up, and if it does it's way to big.
If someone could email me or IM me that would be great.

Or you could just answer on here, thanks! =)

Do you have text to turn into links by turning it into an image map for your new one? If not, I'd just get rid of the entire thing and put, <img src="URL">. You don't need the excess stuff, I don't think. Is this for MySpace?
