Aside from the interesting camera info, data stamped on a photo image file, etc, the basic question that Mike "Undead" asked (several times) still remains unanswered:
Was permission given to go into Poster Mountain's private, secure and non-public database to download their large image files?
OR, was it done by other, "less permissive" means?
Forget about poster images for a moment. Hacking into secure, non-public areas on ANY website is illegal -- period.
Regardless if it be poster images or other data looked at or downloaded -- that is immaterial.
