The unbundling of Google+ features into other Google services continues. This time around Google is porting Google+ Photos into Google Drive. This means you get easier access to your photos right from your Drive account. A Photos menu should be showing up on your Google Drive account soon. And that will show you all the photos you have backed up on the service. It should be coming to your web, Android, or iOS versions of the app soon.
