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.
Slideshow
The frame applies these on its next sync.
On the frame
Nothing yet.
Device
The frame authenticates with a token you paste into its Wi-Fi setup page (hold the wake button ~2 s to open it; leave the Wi-Fi fields empty to change only the token).
Token created . It cannot be shown again. Rotating replaces it, and the frame stops syncing until it has the new one.
Copy it now — it will not be shown again.
Requests carry Authorization: Bearer <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
