does my photostream use memory
Yes, photo stream photos uses your device memory. Photo stream photos are device optimized copies of the photos in your camera roll. If you want to conserve memory, save the photo stream photos to the camera roll on the device where they are not already in the camera roll, then delete the photo stream copy.roblem is that I take most of my photos with my iPhone but do not have enough memory to update my OS to IOS 8, which is required to install the Flickr app. So I was hoping to use my iPad's Photo Stream to share and order prints but if the quality is diminished, maybe that's not such a good idea.
