Avatars on the internet are pretty cool. They let you provide a small picture to tell more about yourself on a certain blog, forum, or community website. But it can be a hassle to have to upload a new photo for each site that you want an image to appear. That’s where Gravatars come in. Gravatars are Globally Recognized Avatars and the idea is that you link your picture to your email address in one place and that avatar can be pulled into a variety of other websites.
You can get your own Gravatar really easily at www.Gravatar.com. Just enter your email address, confirm it when you get the welcome email, and upload your photo! It will then begin appearing when you enter your email address (usually required anyways) on a Gravatar-enabled website.
