Have you ever wondered why some people have a picture beside their blog comment and you don’t?
The little picture (or avatar) is an automatic feature with most blogging software, but if you haven’t setup your avatar, it won’t appear.
Most services are using gravatar.com. Gravatar associates your email address(es) with a photo or graphic that you can upload to their site. You can have many images, each associated with a different email address, or you can have the same picture for all of your email accounts.
Once you associate a picture or graphic with your email address, anytime you use that email address to make a comment on a blog, it will automatically include the image in the comment (assuming the blog is correctly configured).
So go ahead, express yourself and let everyone know who’s doing the commenting!
