The Justice League writers would never forget that kind of detail. Hence why Justice League is the better show.
I agree with you that Justice League rocks the planet, but how do you know that the JL writers wouldn't omit such a minor detail? Have you spoken to them? Those photos was a very minor detail, and overall having BB show them to Terra would not have changed what happened in the story in the least. So why even dwell upon it? My point is that "Things Change" was going to end the way it ended, regardless of whether or not Terra saw the pictures, therefore she didn't need to see them. In the grand scheme of things, the photos were meaningless.
