My girlfriend and I both have iPhones, each running under our separate Apple IDs. We would like to combine our photo streams so that any pictures either of us take will both be uploaded to one photo stream, and in turn into our iPhoto / Aperture library. Currently, only my photos are being uploaded into iPhoto / Aperture and I have to plug in my girlfriend's phone and manually upload her photos, which is not ideal. Is there a solution to combine our photo streams? Alternatively, if this is not possible, is there any way to get iPhoto / Aperture to upload from more than one person's photo stream? I realise that iPhoto / Aperture will soon be discontinued - if there is no solution to this problem, does anyone know if the new replacement app will support this and when it is coming out? Thanks for any help!
