BrandonSavage.net utilizes the gravatar service for the display of user images. This service is free and integrates seamlessly with WordPress and other blogging software to produce the icon you see in the blog comments.
A great way to promote your brand online and help people recognize you when you traverse various sites is to have an icon associated with your name. You can sign up for your own custom gravatar for free by visiting the signup page and completing the steps.
Once you do so, your gravatar will show up on all the blogs you’ve commented on and that make use of the gravatar service. It’s that easy!
