GDrive Photos
A rotating slideshow from a public Google Drive folder. It’s fully independent of iCloud Photos — its own album, its own rotation — so you can run either or both. On the dashboard the card is titled simply “Photos”.
Tap the card for full screen; swipe to browse. It can also drive the screensaver.
Configure
Section titled “Configure”From your phone at idlescreen.app/photo-setup — the widget’s Settings section shows a QR straight to it. The walkthrough covers creating the folder, sharing it by link, checking it works, and gives you a short code for the board. One detail specific to Drive: photos must sit directly in the folder, not in subfolders.
