Its a little bit easier for Google+ users to start sending their photos through Gmail on the web today. Google has just added a new photo attachment button that allows anyone who stores their photos on Google+, either through direct uploads or automatic backups, to see previews of all of their images and add them into an email just by selecting them. Google says that you can attach entire albums of photos too and that youll be able to resize individual images inline. While its not quite as helpful if you arent storing all of your photos with Google, theres a good chance that you can start: Auto Backup is available through the Android Photos app, the iOS Google+ App, and through backup apps for Windows and Macs too.
