Actually, they did do on-ride photos twenty years ago, but the old-fashioned way. How many here have seen _Rollercoaster_? There's a scene where Harry Calder (George Segal) is riding Rebel Yell at PKD. When he gets off the ride, an attendant at a photo stand shows him an on-ride. The camera used looked like a Polaroid with a huge zoom lens. Simple and effective. Of course, this could have been movie magic at it's best.
