Should I use
url(path-to-image) fixed center like it says in the link I provided, because when I do that the background goes white and there's no image. But if I take the 'fixed center' out then the image goes back to how it is now - not fixed.

Nevermind. I did it.
I just added 'fixed' after the image url. Not the 'center' bit. All working good now.
Thanks for your help Lynne.
