Everything you upload to Photos, and every picture you take in iOS, automatically copies to iCloud and syncs to other connected devices. Deleting the image either from iOS or a Web browser would clearly delete it from your central repository, and the warning messages make that clear, too.īut Apple handles iCloud Photo Library differently, because the Photos app in iOS and OS X is an endpoint. On a Mac, you use a Web browser to view images. You don’t need to think about whether the image is permanently on your iOS device. When you use Google Photos, it’s clear that your photos are all stored in Google’s server cloud, and the app is a viewing portal into that cloud storage, even if images are temporarily stored locally in your iOS device.
