Displaying all images of referenced products in product display node

After hours of work i got this solution.

<?php
/**
 * Implements hook_entity_prepare_view().
 */
function HOOK_entity_prepare_view($entities, $type) {
        
  $product_display_entity_type = 'node';
  $product_display_type = 'dishes_product_display';
    
  // create product display gallery with all referenced product images
  foreach($entities as $display) {
    if($type == $product_display_entity_type && $display->type == $product_display_type){
              
      $product_entity_type = 'commerce_product';  
      $product_field_name = 'field_product';
      $photos_field_name = 'field_product_photos';
              
      // get products ID's        
      $product_field_language = field_language($product_display_entity_type, $display, $product_field_name);    
      $field_product = $display->{$product_field_name}[$product_field_language];      
      // get products image fields      
      foreach($field_product as $product_id) {
        $product = commerce_product_load($product_id['product_id']);    
        $photos_field_language = field_language($product_entity_type, $product, $photos_field_name);
        // merge produts images with product display images
        foreach($product->{$photos_field_name}[$photos_field_language] as $image) {
          $product_field_language = field_language($product_display_entity_type, $display, $photos_field_name);
          $display->{$photos_field_name}[$product_field_language][] = $image;
        }       
      }                  
    }
  }    
}
?>
