In Facebook, I want to import a photo (or video) file. When I try to 'execute' that action, I can't find the desired photo, although I just took it yesterday. I need to learn how to organize photos (or, how iCloud organizes them) so I can find them in the future. How do I do that. Appointment at the Genius Bar?
