Thank you :-)

I don't have much of a clue either, sorry!

I use a custom style sheet (CSS) and then all you have to do is add the url from photobucket where i host my header, and the height and width of the header.
The one I am using at the moment is this one.

I could help you with that, but I don't know how to get one on your layout as it is at the moment.
