How to change the avatar?
Gravatar is a global avatar that shows on your blog and follows you around the web anywhere Gravatar service is being used as long as you use your Gravatar registered email on these sites.
Your Gravatar is the image that will appear beside your name when you comment or post on a blog.
A Gravatar is a Globally Recognized Avatar. 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.
The best thing about Gravatar is that it gives you a uniform image across all sites or blog where you comment or publish a post; you don't have to upload your picture to your profile on every blog or forum you are using provided that such site supports Gravatar.
Before you can get your avatar working, you will need to sign up for a Gravatar account.
So, you can see in the comments, Chris and James have a random icon but Enrico has a nice one. Enrico is using Gravar.
