The Carousel widget provides the ability to cycle through elements which is commonly referred to as a slideshow. As it slides through images, they can be configured to display a certain colorization and the ability to add a title, link and/or description. As seen in this example, images can be viewed on AutoPlay or manually by clicking on the arrows (to the right/left) or dots at the bottom of image.
