Hi @Rich_Morin - it depends what you are trying to achieve and what you are comfortable coding in. There are plenty of JS based approaches. If you want to steer clear of that, you could take a look at this: Phoenix LiveView - Change the URL without refreshing the page - not quite a slideshow, but there are a few building blocks in there for displaying and changing images using liveview. You could wire up a server side timer easily enough to update which picture is showing.
