I was a little mystified exactly how to get a Gravatar image working for my local WordPress account (the one I use to post, comment and administer my blog).  Turns out it’s a piece of cake – all you need to do is to create a Gravatar account and add an e-mail that matches the e-mail account you use on your self-hosted WordPress server.

Here’s the quick and dirty:

1. Head over to Gravatar.com by clicking here: www.gravatar.com.
2. Create an account.
3. Link the e-mail address that you use on your WordPress blog/server to post/comment; then add your picture/logo/etc. to Gravatar.  Hint: if you use multiple accounts on your own WordPress site or other sites that use Gravatar, you can simply add the e-mails for those accounts to display the same Gravatar image that you uploaded.
   
4. In my experience your new Gravatar won’t appear without you adding a comment to any blog post.  I added one, saw my picture displayed, then immediately deleted the comment.  At that time all my existing comments (some from years/months prior) displayed my new Gravatar image.

Boom-shaka-laka!  You’re done.
