| WhatsApp group | You create a group and everyone sends there | Compresses every photo, buries them between messages, and you need everyone’s number |
| Drive / Dropbox folder | You share a link to a folder | Needs a Google account, uploading from a phone is a chore, and nobody does it after the party |
| Instagram hashtag | Everyone posts with your hashtag | Only sees what’s posted publicly — most photos never get posted |
| Disposable cameras | A camera per table, develop later | ~27 blind shots per camera, pricey developing, weeks of waiting, no video |
| QR album in the browser | Guests scan the QR and upload from the browser, no app | Needs the QR visible — and a service that skips apps and accounts, or the friction returns |
