Prepare and test your Live Mosaic

Plan the wall, run the go-live checklist, and rehearse moderation, safety controls, exports, and a fallback.

A Live Mosaic works best when the planning, testing, and event-day safety steps happen in order. Work through the three checklists below: plan the wall, test it before doors open, then line up exports and a fallback.

Steps

Plan the wall

  1. 1Choose the final source image before configuring the display. Use a bold logo, icon, or simple key art that will still read from across the room.
  2. 2Confirm where the mosaic will run: TV, projector, LED wall, laptop, embedded page, or recap screen.
  3. 3Match the mosaic aspect ratio to the actual screen orientation.
  4. 4Estimate how many photos the event is likely to collect, then choose a grid density to match. Low is about 500 tiles, Medium about 1,000, and High about 2,300, so pick the density your expected photo count can fill.
  5. 5Decide how new photos should arrive on the wall. In the display settings you can give each new photo a brief close-up, show a strip of the most recent photos, let the view slowly tour the artwork, show on-screen controls for viewers, or keep the animation quiet.
  6. 6Define moderation rules for photos that should not appear publicly, and decide who watches the wall during the event.

Test before doors open

  1. 1Open the Live Mosaic settings and confirm the checklist shows a source image and applied grid.
  2. 2Use Send test photo to confirm the grid can place a tile.
  3. 3Open the public display link on the same type of screen that will be used at the event.
  4. 4Complete several real booth submissions and watch for them to appear on the wall.
  5. 5Hide one test submission from Submissions and confirm it leaves the public display.
  6. 6Test Pause display and Blank screen now so staff know what each safety control does.

Exports and fallback

  • If you want a keepsake image, open the Live Mosaic settings, expand Exports, and choose HD, 4K, or Print. You will get an email when the file is ready, and you can download it from the same Exports list.
  • Prepare a Gallery or Slideshow fallback display link if the venue screen, network, or volume plan changes.

What to know

  • The source image should be simple enough to read from across a room. Small copy, detailed product shots, low contrast, and busy backgrounds can be hard to recognize after they become tile art.
  • If the event expects low submission volume, a lower grid density or a different display type can look better than a sparse high-density mosaic.
  • If you expect fewer photos than tiles, the wall fills in by repeating photos. Use the Photo repeats setting to choose how repeats are picked, and Max uses per photo to limit how often any single photo appears.
  • The wall reads differently on a laptop preview than it does on a large venue screen. Test on the final screen whenever possible, and judge the final look with a realistic number of test photos.
  • Once the wall is live and photos have been placed, the layout settings lock to protect the wall. Pause the display if you need to change the layout, and keep in mind that applying a new grid clears the photos already placed.
  • Pause display freezes what viewers see while new photos keep placing in the background. Blank screen now removes every guest photo from view right away, so viewers see only your source image until you resume. It is the fastest fix if something unwanted reaches the wall.
  • High-resolution exports are useful for recaps, social posts, and prints. Create them from the Exports section after the wall has enough approved content, not before the event has produced meaningful tiles.
  • If the wall is not updating, check that the display is enabled, the source image and grid are complete, the booth submissions have finished processing, and the photos you expect are not hidden.

Tips

  • Use one approved source image file and avoid swapping it after the grid has already been built.
  • Place the screen where guests can notice their photo entering the wall without blocking the booth line.
  • Run the test on the event network, not only office Wi-Fi.
  • Keep one staff member watching the public wall while another completes booth submissions.
  • Keep the direct display link available even if the mosaic is also embedded on a website.
