Display two images per product in category page for PS 1.7

[pixelmary]

Hi everybody and thanks for the support.

I would like to know if you can help me to get two images for each product in product-list.tpl, I have seen several responses about this subject associated with PS 1.6, but obviously, they are not useful for 1.7. I can not find the solution because I prefer not to install a module just for this. I appreciate your help very much! Maybe this links I've found can be useful.

I don't know if you solve it but I solved it and it works perfectly in PS 1.7.

/** FILE /override/classes/controller/ProductListingFrontController.php **/

<?php

abstract class ProductListingFrontController extends ProductListingFrontControllerCore
{

    private function prepareProductForTemplate(array $rawProduct)
    {
        $product = (new ProductAssembler($this->context))
            ->assembleProduct($rawProduct);

        $presenter = $this->getProductPresenter();
        $settings = $this->getProductPresentationSettings();
        
        $productOut = $presenter->present(
            $settings,
            $product,
            $this->context->language
        );
        // Force delete this value from the ProductListingLazyArray > ProductLazyArray. Cya! 
        $productOut->offsetUnset('main_variants', true);
        // Regenerate (performance hit).
        $mainVs = $productOut->getMainVariants();
        $id_image = Db::getInstance()->ExecuteS('SELECT `id_image` FROM `'._DB_PREFIX_.'image` WHERE `id_product` = '.(int)($product['id_product']));
        $link = Context::getContext()->link;
        $product_images = array();
        foreach($id_image as &$image){
            array_push($product_images, $link->getImageLink($product['link_rewrite'], $image['id_image'], 'large_default'));
        }
        
        $productOut->__set('product_images', $product_images);
        //print_r($productOut);
        //echo "\n";
        return $productOut;

    }
}

And then in product.tpl

/** FILE product.tpl inside catalog/miniatures/product.tpl **/

{foreach from=$product.product_images item=image}
   <div class="product-image">
      <a href="{$product.url}" class="thumbnail product-thumbnail">
       <img class="img-fluid" src = "{$image}" />
      </a>
   </div>
{/foreach}

I hope will help someone, for me it's useful and you don't need any module.

See you!
