If you’re looking for a straightforward way to cycle through a list of URLs in a slideshow format, check out urlslideshow.com. It allows you to supply any set of URLs (for example, web pages, images, or videos), and it will rotate through them on a specified timer. There’s no software to install - just set up your slideshow and share the link or run it on a display.
