It'd be incredibly hard to get information for all of the coasters with on-ride photos, and honestly, how would we know? If someone submits that a coaster in Abu Dahbi has an on-ride photo, how are the mod guys going to know whether that's a hoax or not?
Every suggestion has to be put on a scale. On one side, there's how much time it will take to implement and keep around. On the other side, how much it would be used. If the time/effort weighs more than the usefulness, it probably won't happen. And since no word came back from Jeff in almost a month, it appears the scales haven't tipped in your favor. Sorry.
