The Custom WebPart, let's call it "Banner Webpart" cycles through picture libraries dispalying a new image on your site each time you refreh the page. The Banner Webpart also doubles as a banner management system that allows you to set priority status and link your images to external websites. So it should act as both an Image rotator and a banner management system.
