this is indeed a theory that sounds plausable. however, we must delve into the depths of our history and also find "ye olde photographs" to truly see an undoctored photo (taken that this old picture is in its true form, and not scanned onto a computer which could alter it).
however, this also is impossible...as in the dark ages of crappy pictures, we unfortunately didnt have rockets, or ladders high enuf to tell whether the earth was flat or round.
i guess we'll never know if there truly is a picture altering conspiracy, unless a FE can fly up there and throw the RE theory on its head
