  function mw_replace_woocommerce_placeholders() {
  
      add_filter('woocommerce_placeholder_img', 'custom_woocommerce_placeholder_img');
  
      function custom_woocommerce_placeholder_img( $src ) {
          $src = '&lt;span class="thumb-placeholder"&gt;&lt;i class="icon-camera"&gt;&lt;/i&gt;&lt;/span&gt;';
          return $src;
