Plugins Required: Users
Plug & Play: Yes
Enable user avatars with Gravatar, a "global" avatar which has become especially popular since Wordpress adopted it for their avatars.
1. Upload the "gravatar" folder to your plugins folder.
2. Install it from Plugin Management in Admin.
3. Choose the default avatar in Plugin Settings / Gravatar.
Changing the default Gravatar
If a user doesn't have a Gravatar account that matches their email address, then Gravatar will send back the default avatar you use choose in Plugin Settings. If you want to provide a customized avatar, create an 80px .png image called default_80.png and put it in your theme's images folder. Then select "custom" from the choice of default avatars in Plugin Settings / Gravatar.
NOTE: For users of previous versions of this plugin, please note that the collection of random avatars from v.1.0 is no longer used. In fact, v.1.1 doesn't even have an images folder. You can delete the /plugins/gravatar/images folder from your site if you wish.
