When you have a Gravatar account, your image is linked to your email account. This means wherever you comment on the web, if Gravatar is enabled, your image will appear next to your comment 
Gravatar is a great word meaning Globally Recognised Avatar.
This means you can scan a blog, see a familiar face make a comment and stop to read it. It helps people get to know you and your brand across the web. It helps you recognise people in the blogs community and get to know them.
Attaching your image to your email is dead easy.
Click the link and add your email address that you use for making comments http://en.gravatar.com/site/signup/
then an email will be sent to you to activate your account. Click the link in the email.
You will then be asked for a user name and a password, choose wisely your user name – it’s going to be with you a long time!
Upload an image from your PC or choose to add an image of you from the web (Quick Note how to add web image – right click the image, click properties and a grey box appears, use the image location URL.)
You can then crop the image so it fits the box and then when you click crop and finish, you will be asked to rate your image.
Unless you have upload a naughty or graphically violent pic, I suggest you use a G rating, which signifies for general use.
Thats it, all done
Next time you comment on this blog, your image will appear next to your comment it also works on all other WordPress blogs and other Gravatar activated forums.
Let me know how you get on
