I agree the photos could be stegos on both sides. The trick would be, as you say, to know the algorithm used and the password. Using the same password defies security, so there must be a clue to the password in a specific picture. Does this make sense? I'd say a password might be in a Qdrop that would be somehow referenced in the photo (finding these drops has been going on here for a while). Not sure about an outsider's photos. Also, don't know if there'd be a super-secret stego program. Would probably be something that anyone could get ahold of. (was there a stego program on Hunter's laptop, for example, or Weiner's?).
