It's easy to imagine traveling with the Doctor, taking pictures of the various and sundry aliens, civilizations, and other wonders on a cellphone that can call home at any time or any location. Naturally, there's an easy way to make money with that without causing ripples in time: collect them for a book of digital art, claiming that it's all staged and faked. Of course, there might be some conspiracy theorists who claim that there's no way these could be created, that they're too realistic and the various digital data only have errors that make them seem more real. A lso, of course, when U.N.I.T. hauls him in for the pictures he took of those Cybermen, well, there's bound to be trouble. Fortunately, trouble makes for good stories when it comes to Doctor Who. Additionally, I could see BBC Licensing making quite a packet of money off of selling copies of Danny Pink's offworld photos to Doctor Who fans looking at the action from a different sort of perspective than they get from the TV - shaky camera photos have a different level of action to them, and the weird camera angles would provide an interesting new look at what's happening from a companion's-eye view.
