Guests can't upload photos — fix it now

The five most common reasons a guest's upload fails and how to fix each one in under 60 seconds: cellular signal, photo size, browser quirks, hitting the upload limit, and the rare server-side issue.

When a guest tells you “the upload didn’t work,” there are five likely causes. Walk this checklist with them, top to bottom — most fixes take 30 seconds.

1. Bad cellular signal at the venue (most common)

The single most common cause. The guest is in a hotel ballroom, a basement bar, or a hillside vineyard with weak signal.

Fix:

  • Ask if they have Wi-Fi access. If the venue offers guest Wi-Fi, switching to it fixes the issue in 90% of cases.
  • If no guest Wi-Fi, ask them to step into the lobby or near a window. Upload takes 5-10 seconds on cellular — once it starts, it usually completes.

Avoid: Telling them to retry on the same screen without changing networks. The same network issue will hit them again.

2. The photo is too big

Phones now produce photos up to 25 MB per shot. Our upload pipeline accepts up to 30 MB per photo, but a poor connection can choke before transfer completes.

Fix:

  • Have them tap Choose from camera roll instead of Take a photo if they tried the camera. The camera roll versions are usually optimized.
  • For iPhone users: have them check Settings → Camera → Formats → “High Efficiency” is on. This produces HEIC files that are ~50% smaller than JPG, and our pipeline accepts them.

Avoid: Asking them to manually resize. They won’t.

3. The phone’s browser is being weird

Some phone browsers — especially older Android with low storage — fail silently on file uploads.

Fix:

  • Have them close the browser and re-scan the QR. Fresh session, fresh attempt.
  • If still failing, have them try a different browser — Chrome instead of Samsung Internet, Safari instead of Firefox.
  • As a last resort: have them email the photo to a friend’s phone and the friend uploads instead. Awkward but reliable.

4. The event hit its photo limit

Each plan has a per-event photo cap. Essential is 10,000; Signature is 50,000; Premier is 250,000. Hitting the cap returns an error to the guest.

Fix:

  • Check the upload count from event settings. If you’re at or near the cap, contact us at hello@fotowall.io — we extend caps within 5 minutes during a live event.

5. Something’s wrong on our end

Rare but possible. The single signal that tells you this is the case: multiple guests, multiple phones, multiple networks all failing at the same time.

Fix:

  • Check the status page at status.fotowall.io (when published). Confirmed incidents are posted there with ETA.
  • Email hello@fotowall.io immediately if no incident is posted. We respond within 15 minutes during business hours; within 1 hour during an event you’ve told us about in advance.

What to do before the event to prevent issues

Three things, done a week out:

  1. Test from your phone on the venue Wi-Fi. Walk every corner of the venue. If a corner has no signal, set expectations with the planner.
  2. Pre-write a one-line “if upload fails” instruction to give to a roving helper. Something like: “Try the venue Wi-Fi: SmithWedding / password123. Or step into the lobby.”
  3. Have a backup upload URL bookmarked on a tablet at the welcome table. Guests who can’t get their own phone to work can hand you a USB stick (it happens), and you can upload on their behalf from the admin dashboard.
