Knipsmig – no-brainer photo sharing for events

Many sites exist for sharing photos, but I just want to press one button to generate a QR code. Then, I can use it myself and share it with friends. Once scanned, they will land on a page where they can upload photos and videos. Everything will be gathered in one hub, allowing everyone to see the photos. No sign-up, no administration, nothing. It's simple and free.
