Hi JF...I sorta figured out CSS by using info from different sites and putting it all together. I can't remember the sites though...was some time ago...
I use
Code:
background-image: url('urlofbackgroundimage.jpg');
for my background image.
you're free to check out my style sheet if it helps you in any way:

you've prob figured it out by now though...since my reply is so late
