My wife just got an iPhone 4S. I want to turn photo streaming on and send the photos to her iPhoto. I keep all the family photos in my iPhoto library and share it out. My wife can then use my photos as she wants by copying them to her iPhoto. I want her to be able to sort through her photos on photo stream and then I want to move the ones she wants to keep into my iPhoto library. Is the best way to do that simply share her library and copy them every so often? Other suggestions?
