WooCommerce - Add shipping logos after shipping methods

<?php
// add shipping logos after shipping methods
add_action( 'woocommerce_after_shipping_rate', 'shipping_logos', 10 );
function shipping_logos( $method ) {
  $label = $method->get_label();
  switch( $label ) {
    case 'DHL':
      print '<img src="http://www.my-domain.co.uk/wp-content/uploads/DHL-logo.png" class="shipping_logo">';
      break;
    case 'EMS':
      print '<img src="http://www.my-domain.co.uk/wp-content/uploads/EMS-logo.png" class="shipping_logo">';
      break;
    default:
  }
}

/*
The labels in the case statements must correspond to the labels used when setting up the corresponding shipping methods. The logo srcs come from the logos you must have uploaded to your media library.
Works with themes which use the default WooCommerce hooks.
