how to keep iCloud photos from syncing to iPhone
I only have a 16gb iPhone 5s, how do I keep the photos from syncing to the iPhone from iCould?
iMac, OS X Yosemite (10.10.2), 2.7 GHz iCore5, 8MB Ram
If they are from iCloud Photo Library (beta) you can turn it off by going to Settings > iCloud > Photos and set iCloud Photo Library (beta) to off. More details in iCloud Photo Library beta FAQ - Apple Support
If you want to leave it on but significantly reduce the storage needed on the phone, see the quote below from iCloud Photo Library beta FAQ - Apple Support
If you turn on Optimize [device] Storage, iCloud Photo Library will automatically manage the size of your library on your iOS device, so you can make the most of your device's storage and access more photos than ever. iCloud Photo Library stores the original, high-resolution photos and videos in iCloud and can keep lightweight, device-optimized versions on each of your devices. As long as you have enough storage, recent photos and videos that you access the most will stay on your device at full resolution.
To turn on Optimize [device] Storage on your device, tap Settings > iCloud > Photos or Settings > Photos & Camera, then select Optimize [device] Storage. You need an Internet connection to access an original photo or video that’s stored only in iCloud.
If the photos are from Photo Stream you can stop syncing by going to Settings > iCloud > Photos and set Photo Stream to off. More details in My Photo Stream FAQ - Apple Support
