If we use to use iCloud photo Library to store and manage all our photos, can we set some options to prevent it from dumping all those photos onto our iPhones and iPads if we want? Optimized or not, I don't want access to all my cloud photos on my phone. I only want it available to my computer. I do want all photos I take with my iPhone (6) or my iPad Air to go into photo stream and up to my Photos Library. I just don't want any downloaded to my smaller devices. Can this be done? Thanks.
