Use wording guests can understand at a glance
Lead with the action rather than the technology. “Scan to add your photos” is clearer than a bare QR code. Add the couple or event name so guests know they have opened the right gallery, and keep supporting copy short enough to read in a busy room.
Choose the print format for the viewing distance
A5 works well for a welcome table, guest-book station, or bar. An A4 two-up PDF creates two A5 cards with a cutting guide. A high-resolution PNG is useful when a stationer or local printer needs to place the design in a larger layout. Toast Album currently offers Modern Arch, Wildflower, and Classic Frame templates.
Place more than one invitation to share
One entrance sign can be missed after arrivals. Repeat the prompt where people naturally use their phones: on tables, near the photo booth, beside the guest book, or on a screen between formalities. The same private code can be used on every sign for that event.
Test the physical print, not only the screen preview
Print one sample at actual size. Scan it with the standard camera app on both a recent iPhone and Android phone, from the distance guests will stand. Keep the code flat, preserve the clear margin around it, avoid glossy glare, and confirm the link opens the intended event before producing the full set.
Keep the private link within the guest group
The QR code is a convenient form of the event's private link. Do not publish it on a public website or social post if the gallery is meant only for invited guests. Hosts can add an optional passcode and can close submissions from the event management page.
Prepare the gallery before sending artwork to print
Create the event, upload test photos through the guest flow, check the gallery, and download an original. Then edit the card wording and export the chosen format. The photo-sharing FAQ explains supported formats, retention, privacy, and host downloads.
