So, I have the optimizing setting turned on for Photos on my mac, so my disk don't get full.. That means only a low resolution of the photos are stored on the mac, the original ones are on the iCloud. But when I browse through the photos, it automatically downloads the original photos. This happens on the iPhone as well. My question is, there is any way to send back the original photos to iCloud, so they don't stay eating space on the HD?
