It's now easier to share individual pictures on Google Photos. If you want to share a specific photograph, you can do so in a private chat within the app. It will also let you comment and like photos in the conversation and even save what has been shared into your gallery.
It isn't meant to take the place of other chat apps, but Google hopes to make it easier to share images and videos within its app. The feature is rolling out gradually over the coming week on mobile (Android and iOS) and through the web.
