Sorry, I’ve found a solution, insert a short code into the file Funtions.php the end of our theme.

<?php
if ( !function_exists(‘fb_addgravatar’) ) {
function fb_addgravatar( $avatar_defaults ) {
$myavatar = get_bloginfo(‘template_directory’) . ‘/images/gravatar.png’;
$avatar_defaults[$myavatar] = ‘Custom’;
return $avatar_defaults;}
add_filter( ‘avatar_defaults’, ‘fb_addgravatar’ );}
?>
