Show Your NAS Photos on a Tablet Frame

If you run a NAS, you already solved photo storage: everything lives on your Synology or QNAP, organized, backed up, yours. The unsolved part is seeing those photos. They sit in /photo/2019/ and nobody has opened that folder since 2019.

The fix is a tablet on a shelf that reads the NAS directly over SMB. No re-uploading to a cloud, no cloud-storage subscription, no duplicate copies — the frame streams what the NAS already has, and new photos appear on the frame automatically.

What you need

• A NAS with SMB enabled (on Synology: Control Panel → File Services → SMB — it usually already is)
• Any Android tablet or phone on the same Wi-Fi
• A frame app with an SMB client built in — we use PicDock, where SMB/NAS is a free feature

Step 1 — Make a read-only NAS user for the frame

Do not put your admin credentials on a shelf device. Create a user like frame with read-only permission on your photo share and nothing else. Two minutes now, and the frame can never delete or modify anything.

Step 2 — Connect the app to the share

In PicDock: Photo source → SMB/NAS → Add server. Enter the NAS address (e.g. 192.168.1.20 or synology.local), the frame user, and pick the folders to show. Subfolders are included, so pointing it at /photo covers the whole archive.

Step 3 — Settings that matter for NAS frames

• Auto-refresh: the frame rescans the share periodically, so last weekend's photos join the rotation without you touching the tablet.
• Shuffle by default: archives are chronological; shuffle mixes 2015 with last week, which is exactly the serendipity a frame is for.
• The capture date on screen: NAS files often carry a copied-file timestamp. PicDock reads the real capture date from EXIF, so the overlay says when the photo was taken, not when it was moved to the NAS.
• Face filter: a NAS archive contains everything — screenshots of router configs included. The face filter limits the show to photos with people, and it runs free and on-device.

Wi-Fi and performance notes

• SMB streaming is light: the frame fetches one photo at a time, resized for the screen. Even a 2016 tablet on 2.4 GHz keeps up.
• If the tablet sleeps on Wi-Fi, exempt the frame app from battery optimization — a frame that loses its NAS every night is a sad frame.
• Videos on the share can play in the rotation too; keep them short or let the interval setting cap them.

Why not just use the NAS vendor's app?

Synology Photos and QNAP's apps are good at browsing and backup, but their slideshow modes are built for occasional viewing, not for an always-on frame: no clock, no weather, no auto-start on power, no night schedule. A frame app treats the slideshow as the product, not a feature.
