This plugin is similar to the Slideshow plugin, but displays multiple images at the same time. You can create multiple carousels, make your carousel horizontal or vertical, auto-scroll, change the number of images to display at once, enable/disable arrows and bullets for navigation, and more.
To manage your carousel, go to the menu DisplayBuddy > Carousel. You can add images and change settings there. You can add carousels to widgets or directly in posts/pages. To add a carousel to a post/page, use the shortcode format [pb_carousel group="#"], where # is the ID of the carousel you want to display. See the DisplayBuddy > Getting Started menu for more details.
Note: if you are on Efficient Websites Managed Hosting, you do not need to purchase this plugin; you have access to it at no additional cost.
