Gmail users could send images stored on Google+ by adding them directly to new emails. Google was encouraging smartphone and tablet owners to back up their photos automatically to the social network through the Google+ mobile app by offering unlimited storage.
Users had access to all the photos that were stored on their Google+ account. It was possible to send an entire album by adding it to a Gmail email. The number of photos that could be added to an email was limited the total size of 20MB, whereas an album could contain a number of images and was sent as a link in the email.
Users accessed as many photos that were stored on mobile devices under the Google+ account and had the option to share an entire album.
An additional feature included photos being able to be resized in the composed message. The corners of the photo were dragged to the desired size.

The new ‘insert photo’ button appeared at the bottom of the message next to the text and ‘send’ button. Google users needed to turn on Auto Backup on their smartphones to enable this function in Gmail.
