Avatars Meta Box

Select your post author in style. Choose post authors by avatar instead of a select drop-down.

<p>This plugin allows you to automatically add Gravatars for commenters to your<br />
theme, if your theme does not already support them.</p>
<p>According to the Gravatar.com website, Gravatars are Globally Recognized<br />
Avatars, or an “avatar image that follows you from weblog to weblog<br />
appearing beside your name when you comment on gravatar enabled sites.”<br />
You register with the Gravatar server, and upload an image which you will<br />
use as your avatar. The gravatar image is keyed to your email address, so<br />
that it is unique to you.</p>
<p>This plugin will display gravatars for the people who comment on your posts.<br />
You do not need to modify any of your template files — just activate the<br />
plugin, and it will add gravatars to your comments template automatically.</p>

addresses to lowercase before hashing with MD5:<br />
