note4 photos 400×300 · 4 greys

Add photos

Each photo is centre-cropped to the panel, dithered to four greys and stored for the frame; nothing else from your library is read.

Device

The frame fetches with Authorization: Bearer <DEVICE_TOKEN>. Photos are served in a fixed order, so a counter is enough:

GET /device/photo?i=<n>     → n-th photo (wraps), 30010-byte .epi
                              headers x-photo-index, x-photo-count
GET /device/photos.json      → list
