Gmail Shelfie is built on the idea that you shouldn’t be selfish with your selfie. With just a few clicks, your mom, your aunt, or that girl you have a crush on can set your Shelfie as their Gmail theme so they can enjoy checking, reading, and writing emails while seeing your friendly face in the background.
Got an awesome selfie? Upgrade it to a Shelfie! Simply open or refresh Gmail on the desktop and share it with your friends. (Gmail Shelfie is rolling out over the next few hours.) If you're looking for inspiration, set your theme to Gmail's top trending Shelfies. You can also see who's currently trending on our Google+ page.
Spoiler alert: Word of the Year 2014 will be Shelfie... clearly.
