Avatar override | WordPress.org

Hi there!

To modify avatars you can use this filter:

This is example for that plugin

add_filter('better_messages_rest_user_item', 'custom_user_avatar', 20, 3 );

function custom_user_avatar( $item, $user_id, $include_personal ){
	if ( ! defined('SUA_USER_META_KEY') ) return $item;
	
	
    $attachment_id = get_user_meta( $user_id, SUA_USER_META_KEY, true );
    if ( empty($attachment_id) || !is_numeric($attachment_id) ) {
	 	return $item;
    }
	
    $attachment_src = wp_get_attachment_image_src( $attachment_id, 'medium' );
	
	if( $attachment_src ) $item['avatar'] = $attachment_src[0];
	
    return $item;
}
