Yep, I just implemented Gravatars on the comments. What are Gravatars you might ask? Well, I already gave you two links to the site to find out what they are.
The rating for Gravatars on this blog is PG and the default size is 40×40 since I think it suits best this blog theme.
A Gravatar is basically a “global” avatar that you can use on any blog or site that has it implemented. Think of it as your IM Avatar, only for blogs. The only difference is that you register through Gravatar.com and you have to wait for it to get a rating. For more information on the image ratings click here.
How does the site recognize which Gravatar is yours? By your e-mail. So in order for your Gravatar to appear here you need to use the same e-mail you used to register, but don’t worry, your e-mail will not be displayed on the blog for spammers, nor will it’s source address contain it.
