[Plugin: JJ NextGen JQuery Slider] Change image on hover?

Hello I was wondering if there was an option of having an image change when you hover over an image.

I know there is the
pauseOnHover: Stop animation while hovering. (sc: pauseonhover=”setting”)
But I dont know if there is a change when you hover.
Or is there a way to change the js so that you can make it change on hover?
