You are not incorrect about anything. The only exception to the challenge you are making could be in that assumption that the images were intentionally doctored with to disguise/obfuscate/alter reality. In face: They were intentionally doctored, there has been an editor on these files. The originals will no doubt provide further math.

EDIT: Note that JPC seems to be preparing for a naming-of-feature challenge, which in itself is an interesting aspect of the whole story! Go for it, I say!
