One more thing, notice she calls it "1FLAMEN6 Puzzzle". AFAIK this is the first time we have a conformation that "N6" is not a random product of vanity generator but something intentionally put there. Does it mean "in six" is open to discussion.

I think what she said could have been taken a couple of ways... Either the image has all information contained within it, or the image is a trailhead for a new puzzle that doesn't require knowledge of the previous puzzles. I am leaning towards the latter.
