Hi; I'm wondering how to go about coding an effect whereby the rollover of list
items will change the background image behind the whole list? To put this in
context, I'm hoping to set up a navigation bar with a list of artist names, and
when the user rolls over each name, the image in the background--ie. behind the
entire list-- changes accordingly so as to present an example of the
highlighted artist's work.

I know how to set up basic rollover images via javascript, but I can't figure
out how to establish the effect with a background image; I would imagine this
can be achieved via CSS?

Thanks for any assistance;

Nick
