Change the Default Gravatar in WordPress

Gravatar is one of the things that ruins your site speed (because the avatar is read from an external site).

If you want to change it, put this code at the end of your theme’s functions file. Download a good-looking avatar and use its address in place of the link, so you end up with a nicer Gravatar and better speed at the same time. Then go into the Gravatar settings in WordPress and enable Default Gravatar.

add_filter( ‘avatar_defaults’, ‘wpb_new_gravatar’ );

function wpb_new_gravatar ($avatar_defaults) {

$myavatar = ‘http://example.com/wp-content/uploads/2017/01/wpb-default-gravatar.png’;

$avatar_defaults[$myavatar] = “Default Gravatar”;

return $avatar_defaults;

}
