>so why say the image is worth remembering?
It doesn't, it implies something in the image is related to something worth remembering. It's tying together two otherwise unrelated pieces of data (the watch & it's digs and the "week to remember" drop) with a connection we know is as legitimate as it can get around here (connected by Q directly). We've already been given the pieces of the puzzle already, now we're being given brief glimpses at the box to try and figure out how they all fit together.
