I don't think the second picture shows anything definitive either, Hibbert is behind Aldridge and you can't see their legs so you have no idea if they are bent or if the are in the midst of walking/running making them appear taller.
the second photo is taken from a low angle with Hibbert standing behind Aldridge which again easily accounts for them appearing about the same size. I recall OMSI has/had little exhibits on this sort of optical dilution. Roy has always seemed a size larger then 6'10 250lb LA to me STOMP
I was just curious... I know guys who like to play PF will fudge on their height because they don't want to be considered a 7 footer.
Aldridge looks closer to the camera to me. I don't doubt that Hibbert is 2-3 inches taller than Aldridge. Ed O.
