Gravatar is a “Globally Recognized Avatar.”
Aside from the popular movie, most are familiar with avatars, the images used to represent you online. Every website, forum, and social media service encourages their usage. We have to have one for each online activity we enroll in. The development of the Gravatar is an attempt to create a universal avatar with the ability to be incorporated into multiple services – one stop picture and branding.
While this isn’t true for the majority of social media and interactive sites, it is true for the WordPress Community. In October of 2007, Automattic purchased Gravatar and integrated it into WordPress.com two months later for testing, and soon afterward Gravatar was integrated into the core of WordPress.
Through WordPress or directly through Gravatar, register and set your Gravatar image. Your image will then be linked to your email address. Sign into any WordPress site with that address, or leave a comment with that address, and your avatar image will be automatically displayed in the comments or other areas on the site. This includes all WordPress sites around the world including WordPress.com.
