Effortlessly Manage Your Digital Displays

Google Photos Display Setup

Control devices that don’t run CURA directly

CURA can publish content to a Google Photos album, allowing you to manage devices like Chromecast, Nixplay frames, Roku Backdrops, and Google Nest Hub – even though they don’t run the CURA app.

Devices you can control via Google Photos:

  • Chromecast Ambient Mode
  • Google Nest Hub / Nest Hub Max
  • Nixplay frames
  • Aura frames
  • Lenovo Smart Frame
  • Roku Backdrops
  • HiSense CanvasTV (Art/screensaver mode – or run CURA natively on Google TV)
  • Any device that displays from Google Photos

How It Works

  1. CURA creates a Google Photos album for each display (named CURAX-{YourDisplayName})
  2. CURA publishes your content to that album based on your settings
  3. Your device displays from that album
  4. You control everything from CURA – collections, scheduling, filters

Step 1: Connect Google Photos

  1. In the CURA app, go to Subscription → Linked Accounts tab
  2. Tap Connect Google Photos
  3. Sign in with your Google account
  4. Grant CURA the requested permissions (see below)
  5. Done – CURA will create albums automatically when you set up displays

Permissions Explained

When you connect Google Photos, CURA requests permission to:

Permission What it allows Why CURA needs it
Create albums Create new albums in your Google Photos CURA creates CURAX-{DisplayName} albums for each display
Add photos to albums Upload images to CURA-created albums CURA publishes your content to these albums
Read CURA-created content View albums and photos CURA created CURA manages album contents (move old images to archive)

What CURA cannot do:

  • ❌ Read your personal photos or albums
  • ❌ Delete any photos (this is why CURA_ARCHIVE exists)
  • ❌ Modify photos you didn’t upload via CURA
  • ❌ Access shared albums or smart albums

Privacy note: CURA only accesses albums it creates. Your personal Google Photos library remains private and untouched.

Step 2: Create a Google Photos Display

  1. In CURA, go to Rooms
  2. Tap Add a GP Display (in the Rooms header)
  3. Give it a name (this becomes part of the album name)
  4. Choose your Publish Mode (see below)
  5. Assign a collection
  6. Save

Publishing Modes Explained

CURA offers three publishing modes for different devices and use cases:

Single Mode (Best for Chromecast)

Setting Value
Best for Chromecast Ambient Mode
How it works CURA uploads 2 copies of one image, refreshes periodically
Who controls timing CURA controls how often the image changes
Minimum duration 2 minutes
Recommended duration 2-10 minutes

Use Single mode when: You want CURA to control exactly when images change on your Chromecast.

Batch Mode (Best for Frames & Backdrops)

Setting Value
Best for Nixplay, Aura, Roku Backdrops, Lenovo Smart Frame
How it works CURA uploads multiple images (1-50) to the album
Who controls timing The device controls its own slideshow
Minimum duration 30 minutes
Recommended duration Match your device’s polling interval (usually 1-2 hours)

Use Batch mode when: Your device has its own slideshow feature and polls Google Photos periodically.

Full Mode (One-Time Sync)

Setting Value
Best for Initial setup, static collections
How it works CURA uploads all images from the collection
Who controls timing The device controls its own slideshow
Minimum duration 1 hour

Use Full mode when: You want to populate an album once and let the device handle everything.

Step 3: Configure Your Device

Chromecast / Chromecast with Google TV

  1. Open Google Home app on your phone
  2. Select your Chromecast device
  3. Tap the gear icon (Settings)
  4. Select Ambient Mode
  5. Select Google Photos
  6. Select the CURA album: CURAX-{YourDisplayName}
  7. Important: Set “Personal photo curation” to “Live Albums only”
  8. Set slideshow speed to 10 seconds or 30 seconds

Why “Live Albums only”? This ensures Chromecast only shows images from your CURA album, not random photos from your Google Photos library.

Google Nest Hub / Nest Hub Max

  1. Open Google Home app
  2. Select your Nest Hub
  3. Tap Settings → Photo Frame
  4. Select Google Photos
  5. Select the CURA album: CURAX-{YourDisplayName}
  6. Adjust slideshow settings as desired

Nixplay Frames

  1. In the Nixplay app, go to Settings → Connected Services
  2. Connect your Google Photos account
  3. Select the CURA album: CURAX-{YourDisplayName}
  4. Set the frame to display from this album

Note: Nixplay polls Google Photos approximately every 1-2 hours. Use Batch mode in CURA with a duration of 30-60 minutes.

Roku Backdrops

  1. On your Roku, open Backdrops
  2. Go to Settings → Photo Sources
  3. Connect Google Photos
  4. Select the CURA album

Note: Roku Backdrops polls every 2-3 hours. Use Batch mode with a duration of 2-4 hours.

Aura Frames

  1. In the Aura app, connect your Google Photos account
  2. Select the CURA album to sync
  3. The frame will display photos from this album

Lenovo Smart Frame

  1. In the Lenovo Smart Frame app, connect Google Photos
  2. Select the CURA album as a source
  3. Configure display settings in the app

Portrait / Vertical Displays

CURA supports vertical displays via Google Photos publishing. CURA rotates images server-side before uploading so they display correctly on portrait-mounted screens.

For Chromecast in portrait mode:

  • Disable Weather, Time, and Device info overlays in Google Home
  • These overlays are controlled by Chromecast and won’t rotate with the image
  • Result: sideways text on your vertical display

Tip: Set your display orientation in CURA (Portrait CW or Portrait CCW) and CURA handles the rest.

Video Support

Important: Video is NOT supported via Google Photos publishing.

Chromecast Ambient Mode, Roku Backdrops, and digital frames only support images from Google Photos albums. For video playback, use a CURA native app (Fire TV, Roku, Apple TV, Android TV, tablets).

Troubleshooting

Chromecast shows random photos instead of CURA content

Cause: “Live Albums only” not selected

Fix: In Google Home app → Chromecast → Settings → Ambient Mode → Set “Personal photo curation” to “Live Albums only”

Album is empty / No images showing

Causes:

  • Google Photos not connected
  • OAuth expired
  • No collection assigned to display

Fix:

  1. Check Subscription → Linked Accounts → Google Photos is connected
  2. If showing “Disconnected”, tap to reconnect and re-authorize
  3. Verify a collection is assigned to your Google Photos display

Images aren’t updating on Nixplay/digital frame

Cause: Device polling interval is longer than CURA’s refresh

Fix:

  • Use Batch mode (not Single)
  • Set CURA duration to match or be slightly shorter than your device’s polling interval
  • Nixplay: ~1 hour | Roku Backdrops: ~2-3 hours

“Rate limit” or quota errors

Cause: Publishing too frequently

Fix:

  • Single mode: Increase duration to 2+ minutes
  • Batch mode: Increase duration to 30+ minutes
  • Reduce batch size if using many Google Photos displays

Wrong images showing (old content)

Cause: Stale cache or sync issue

Fix:

  1. In CURA, go to the display settings
  2. Tap Refresh or Re-sync
  3. Wait a few minutes for the device to pick up changes

Tips for Best Results

  • Match durations to device polling – No point refreshing every 5 minutes if your frame only checks hourly
  • Use Batch mode for frames – Single mode is optimized for Chromecast; frames work better with Batch
  • Check “Live Albums only” – The #1 Chromecast issue is this setting not being enabled
  • Portrait needs CURA rotation – Set orientation in CURA display settings; disable Chromecast overlays
  • One album per display – Each CURA display gets its own Google Photos album for independent control

Frequently Asked Questions

Can I use my existing Google Photos albums? No – CURA creates and manages its own albums (named CURAX-{DisplayName}). This allows CURA to control the content without affecting your personal albums.

Does this count against my Google Photos storage? Yes – images published by CURA are stored in Google Photos and count against your storage quota. See the Storage & Maintenance section below for details on managing this.

Can I use Flickr content on Google Photos displays? Yes! Assign a Flickr-sourced collection to your Google Photos display, and CURA will publish those images to the album.

Why not just use Google Photos directly? CURA adds scheduling, safety filters, collections, multi-display coordination, and Flickr integration – none of which Google Photos offers natively.

Storage & Maintenance

Understanding Google Photos Storage

Images published by CURA are stored in your Google Photos account and count against your storage quota. This is how Google Photos works – any image in your library uses your storage.

Storage usage depends on your publish mode:

  • Single mode: 2 images at a time (minimal storage)
  • Batch mode: Up to 50 images at a time (moderate storage)
  • Full mode: All images from the collection (can be significant)

The CURA_ARCHIVE Album

Important: Due to Google Photos API limitations, CURA cannot delete images from your Google Photos account.

When CURA refreshes your display album (removes old images to add new ones), the old images are moved to an album called CURA_ARCHIVE. CURA reuses images from the archive when possible, but over time this album may grow.

Periodic Maintenance

If you notice your Google Photos storage filling up, you may need to manually clean the archive:

  1. Open Google Photos (photos.google.com or the app)
  2. Go to Albums
  3. Find CURA_ARCHIVE
  4. Review the images – these are old images CURA has cycled out
  5. Select images you no longer need
  6. Move to Trash (they’ll be permanently deleted after 60 days)

How often? Most users won’t need to do this often. Check quarterly, or if you notice storage warnings from Google.

Tip: If you use Full mode with large collections, you may need to clean the archive more frequently.

Minimizing Storage Usage

  1. Use Single mode for Chromecast – Only 2 images at a time
  2. Limit batch size – Use smaller batches (5-10 images) instead of maximum (50)
  3. Avoid Full mode for large collections – Or clean the archive after initial sync
  4. Check your Google storage – Go to google.com/settings/storage to see usage
