Apple continues to offer users increased control over their iCloud data. One recent feature makes it easy to copy an entire iCloud Photo library to Google Photos. Instead of downloading photos locally and then uploading them to another service, Apple's Data and Privacy hub transfers them directly from iCloud to a Google account. The only limitation is storage space requirements.
iCloud Photo Library
A great way to relive vacations or journeys abroad, or to keep family, friends and loved ones on your mind, is to display photos of them. One of the best ways to do that is to set them as a background wallpaper or screensaver (or both) on your Mac. This is easily done, as long as you are syncing photos with iCloud on both your Mac and your iPhone and/or iPad.
The iCloud Photo Library was designed to let you easily sync your photos between all of your devices. If you have it enabled on your iPhone, then you can turn it on on your Mac or iPad and instantly access all the pictures you've taken with your iPhone. Additionally, any photo edits you perform on your Mac will immediately be reflected in those photos on your other devices.
Enabling iCloud Photo Library will let your photos automatically upload to your iCloud where they can be accessed by your Mac, iPad or any other device with access to it. To turn it on, head to Settings -> Photos and toggle it on.
Sharing photos with friends and family is arguably the main reason people take photos in the first place. There are countless methods of sharing photos - you could share a folder of photos on Dropbox, upload to Facebook or Flickr, add to your story on Instagram, and the list goes on. Each has its own take on photo sharing and some may suit you better than others, but if you have an iPhone or iPad, iCloud Photo Sharing is an excellent option.
