Hello, I have a nas drive that I have stored all my photos on in a raw format (cr2) but I don't seem to be a blue to view them on my ipad, eveytime I try to open, it doesn't recognise the file, and asks if I wanna use document viewer or video player, well, as its not either of those it won't work. The photos are of my baby and I really wanna be able to view them on here, apple help were useless, PLEASE HELP!!,!,
