I recently had to create a slideshow for a special project. What's so special about that you say. Indeed, everywhere you look you see slideshows. If there's one thing that's common to 99% of all websites today it's a slideshow. Almost boring. That is until you actually decide to implement one. There must be 50 ways to slide your images - and I don't mean the transition effects. There's a page with extensive documentation just for that (see References in the sidebar). Picking and choosing the right module and library is almost a burden.
There are various scenarios where you would want to display a slideshow. The most common is the home page. I've used the venerable Views Slideshow module (2007) in the past for this purpose. It's simple enough to implement and is available for D7, D8 as well as Backdrop.
