You might want to try a web-based tool like urlslideshow.com. It lets you create a slideshow from any set of URLs—web pages, images, or videos—and automatically cycles through them on whatever interval you set. There’s no software installation required; just enter your links, adjust the timing, and share or display the resulting slideshow.

(For transparency, I’m the creator of urlslideshow.com. I built it specifically to streamline this kind of URL-based slideshow setup, so hopefully it fits your needs.)
