Well, unfortunately for you (and the other poster as well), you mised the
fact that I said "encrypted" (or you just failed to understand the
importance of this idea).

No program, or human, on this planet would spot a strongly encrypted JPG as
a JPG. They would see it as nothing but meaningless noise and they would
have no hint as to what type of data it might be other than random noise.

No human, or computer program, on this planet, could be smart enough to
correctly recognize data like that as an encrypted JPG file.
