Step Carousel Viewer displays images or even rich HTML by side scrolling them left or right. Users can step to any specific panel on demand, or browse the gallery sequentially by stepping through x number of panels each time. Contents for the Step Carousel Viewer can be defined either directly inline on the page or via Ajax and extracted from an external file instead. Supports ability to specify whether panels should wrap after reaching the two ends, persistence of last viewed panel, and automatic generation of left/right nav images.
