can coda-slider which slides panels horizontally be made to slide panels wider than the screen?

I've made a website that uses coda-slider to slide the entire screen to the left when the user clicks on a menu item.  It takes him to the correct screen.  Its a neat effect, and other people have done it too.
My question is - suppose I have a background image that is rather wide.  I can stretch it so it fits the height of the screen, but then its too wide for many monitors.  When I slide to another screen, I want the entire background image to fly past the user, even if it is wider than the screen.
Can this be done?
