I finally saw the Joel Gilbert film earlier this week, BTW. Gilbert's theory on the dock picture is that is from the 1959 arrival of Obama Sr. Stanley Armour Dunham's presence is explained by assuming he had already begun "commuting" from the Seattle area to Hawaii at this time to start keeping an eye on the foreign students for the CIA.
The face of the Kenyan Obama in the dock photo is shopped from one of the airport photos. The dock photo is so messed with that it is impossible to know what and who it all was originally. Whoever is wearing the Kenyan’s face appears to be a lot taller than the Kenyan.
