How to Add Navigation Bar Images?

[Gray Matter]

Hi,

I've been playing around with my templates, but I cannot seem to get something right. I'd like to have the nav bar have an image for a background, just on a few of my styles. The image would have to not repeat and be aligned wherever I'd like it to be. It would be cool if I could have it as a table or TD background rather than just an image sitting there, that way users cannot just "rip" the image as easily. Any help would be greatly appreciated.
