@futurebird I keep wanting to build a simple webapp that feeds a digital GM screen, but I have too-many-projects-syndrome, so I'll probably never get around to that: One UI would allow you to choose a picture from a gallery, the other simply shows the chosen picture full screen on a different device, changing it only when a "change now!" button is pressed.

@futurebird years ago, I created a PHP script that served up a map for my Neverwinter Nights gameserver from the minimap tiles. There even was a GM-version that allowed me to look at the underground layers of the map, and add annotations of where special locations were.

Alas, the GM version is gone, only the simple overview survived... https://orkpiraten.de/map/
