Changing the "Knoppix" side image in the K menu.

I've managed to get all my menus set up the way I like them, the only thing I can't seem to change for the life of me is side image. It's the image that says knoppix that runs up the side of the K menu. Could someone tell me how to change it? Thanks in advance!

did you figure this out?
I'm still trying to right now.

You can do that if u go into
/usr/share/apps/kicker/ and then there is a picture called kside.png
That's the one u r after
