A Gravatar is a Globally Recognised Avatar, it is an image that follows you from site to site appearing beside your name when you do things like comment or post on a blog. Avatars help identify your posts on blogs and web forums. If you leave a comment on my site and you have a gravatar you will notice the image beside the comment you have just left.
An “avatar” is an image that represents you online, it’s a little picture that appears next to your name when you interact with websites.
You upload it and create your profile just once, and then when you participate in any Gravatar-enabled site, your Gravatar image will automatically follow you there.
Gravatar is a free service for site owners, developers, and users. It is automatically included in every WordPress.com account and is run and supported by Automattic.
