Google Photos, which launched in May, has made a huge impact in its short life, attracting upwards of 100 million people to download the app and use the Web service.
Google Photos today launched “Shared Albums,” a way to privately get photos to loved ones and friends, and in turn, have them grow the album with additional photos.
It's available via updates to its app for Apple and Android devices, and on the web.
Prior to Shared Albums, Google Photos users could select a bunch of photos and send out a link to friends and family for sharing.
But they couldn’t add to it, and build an album.
