I have enable Photo Stream in iCloud. When I put pics into the photostream upload folder on the computer, those appear quicklly in the photo stream album on my iPhone 4s. Now I want to move the photos and videos from “camera roll” to “photo stream”, so that I can view them on my Mac.
You can’t transfer photos from Camera Roll to PhotoStream. Only photos taken by iPad/iPhone are added to Photostream. Any photos that are in the Camera Roll don’t come to another device itself. You can plug phone into Mac using USB cable, and copy those pics and videos to a folder on the Mac.
