So I just purchased an iCloud plan. I have turned iCloud on on my iMac, my iPhone and an iPad. I was under the impression that my photos from the new Photos app on my iMac would upload to a magical cloud and I would be able to retrieve them on my iPhone and iPad. It doesn't seem to be uploading to the iCloud. I followed the directions, what might I be missing? And.... being the eternal optimist, once my photos are all in this magical iCloud I can stop syncing them on to my phone to have them with me correct? Leaving much memory space free on my iPhone.
