This portlet is a showcase of Cover Flow also known as Content Flow.

Most often we need a slider, carousel or some kind of animation. This portlet helps with setting up a content flow or cover flow for a site.

All you need to do is create a folder in document library root folder and add images and their description. By default, cover flow supports showing 6 images which can be increased by configuration or key in portlet.properties file. You can also select the folder containing images in portlet configuration.
