Skin scrollbar with my own images?

I know there are a zillion posts about skinning scrollbars, but I can’t find one about replacing the images with my own…

anyone know where I can find info on this?

I have my own scrollTrack and dragBar that I’d like to replace… either UI component, or I’ll learn how to create a scroller myself, but I would like to minimize time by using the UI component if that’s possible…

If I cannot change the images in the UI component, is there a tut somewhere about scrolling dynamic text, using CSS and a totally custom scrollbar?

help?
