Randomly Changing/Cycling Images

My search-fu hasn't turned up anything yet but does anyone know of a script that will, every n minutes, change an image to one from a random selection (either from a rollable table or a manually curated list of Art Library links)? Looking to have a "World Information" section of my players' landing page that cycles through little tidbits of information.

There is a script called Loading that does this for text: &nbsp; <a href="https://app.roll20.net/forum/post/1226651/slug%7D" rel="nofollow">https://app.roll20.net/forum/post/1226651/slug%7D</a> It could be pretty easily modified to have a list of image urls and swap out the imgsrc on a graphic instead.
Aha, looks great. Knew someone must've made something along these lines! This might work even better actually; instead of loading images, the world info can just be pure text. Only thing to change is to have it target a specific text object (as it'll be on a page with many such objects); perhaps a way to "set" which text object to use.

Yeah, I'd probably add a command to toggle a text block as being updated by the script and store the id in state, probably add a gmlayer label to tell you what it's being used for, then only update if someone is on the page.
