Now you can easily (in just a click) override default WordPress recent comment widget to display avatars with it , just like P2 Theme’s recent comment widget. WP Recent Comments With Avatars is a lightweight but powerful WordPress plugin that automatically overrides default recent comments in WordPress and adds an avatar display for visitor comments and quotes length of 50 characters.
Installation & Usage: Simply install and activate WP Recent Comments With Avatars and you are done. Use same old default recent comments widget and now it will display avatars with it.
The plugin is a direct descendant of WP_Widget_Recent_Comments.
Example markup that is generated by the plugin (for theming):
<ul id="recentcomments"> <li> <div> <img width="32" height="32" src="https://0.gravatar.com/...%3D32&r=G" alt=""> </div> <b>UserName</b>: excerpt comment <a href="http://example.com/page/#comment-ID">»</a> </li> <li> ... </li> </ul>
