Background image…

Hi,

I am absolutely new to WordPress (or for that matter in any web technology) and ‘Wilson’ is my first theme. I am still sort of groping in the darkness. I would like to add a background picture to the left-sidebar (but preferably not to the right-sidebar) and want the navigation / menu to float on it.

I tried this in style.css by replacing the background in .body{} with background-image: url(). But this made my image tile / repeat all over left & right bars in an ugly manner.

Basically, I fancy a left sidebar just like the one – HERE .

IS THIS POSSIBLE? PLEASE HELP!
