That was one of the initial things I was unsure of back when this was more of a side project. I sent the first batch of images from my siblings to print locally, unsure how they'd look. Surprisingly they looked pretty awesome even though the resolution of the images seemed low. They're not pro-quality, wedding photos but they are solid and solve the problem for the audience (old people). Carriers have a tendency to downsize images too far, especially if you send 5 or 10 images at once. When this happens, our bot complains at you. The limits of MMS can be a bit annoying so I recently rolled out email support. This also allows us to support enlargements which we can't do with MMS. Still, having a unique number is sweet because SMS is the first option when sharing a photo (on iOS, at least) and it's easy to snap a photo, send it to NanaGram, and close your display without getting sucked into the notifications abyss.
