The whole camera roll — puppy to now — as one giant poster.
Nobody takes one photo of their dog. They take four thousand, and the good ones sit in a phone where nobody sees them. A grid poster gets them all onto one sheet, in the order they happened, so you can watch them grow up across the wall.
This page sets framing to Whole photo, because the face finder only looks for human faces — that way ears, tails and the daft ones mid-shake stay in the frame.
