The LCA Plugin allows commenters to upload and display an avatar based on either name, e-mail address, url or a combination of all three entered.
<?php lca_form(); ?>within your template in the place where you wish the upload form to appear.
<?php lca_avatar( $comment ); ?>within your template in the place where you wish each commenter's avatar to appear. This must be placed within the comment loop on the Comments page.
The upload directory must be writable by the PHP script. The script will warn you if this is not the case and ask you to take action before using the plugin. This usually means setting the permissions to 666 or such like.
Styling the Form and Avatar
Both the form and avatar have been given special classes for use within CSS.
