For bonus points, you can implement your own default gravatar.
// THIS ADDS CUSTOM DEFAULT GRAVATAR
if ( !function_exists('fb_addgravatar') ) {
function fb_addgravatar( $avatar_defaults ) {
$myavatar = get_bloginfo('template_directory').'/images/icon.png';
//default avatar
$avatar_defaults[$myavatar] = 'The Voodoo Empire';
return $avatar_defaults;
}
add_filter( 'avatar_defaults', 'fb_addgravatar' );
}
in your themes functions.php ('/images/icon.png'
) will need to be edited to your image (which will need to be uploaded to the images folder in your theme)
Then under settings->discussion your new icon will show up. You can select it, and then when people don’t have a gravatar set up, it will use the icon you uploaded
Dunno if this interests you, but I just discovered how to do it…..and I think its cool, so figgered Id share
