Displaying images on category page, and custom thumbnails

[saracoratello]

Hello,

 

I have prestashop 1.4.7

 

My problem is that i want to show on category pages two images, not only one. And i do not have too much idea how to do this.

 

adding this code to Controller/CategoryController.php in process function

 

 

$image_array=array();
for($i=0;$i<count($cat_products);$i++)
  {
   $image_array[$i]= $this->category->getProductsimg($cat_products[$i]['id_product']);
  }
self::$smarty->assign('productimg',(isset($image_array) AND $image_array) ? $image_array : NULL);

 

and this into my-theme/product-list.tpl

 

{foreach from=$productimg key=key1 item=pimage}
 {foreach from=$pimage key=key2 item=pimage2}
   {if $product.id_product==$pimage2.id_product}
     <img src="{$link->getImageLink($product.link_rewrite,$product.id_product|cat:"-"|cat:$pimage2.id_image, 'home')}" alt="{$product.legend|escape:'htmlall':'UTF-8'}" {if isset($homeSize)} width="{$homeSize.width}" height="{$homeSize.height}"{/if} class="{$key2}" />
    {/if}
  {/foreach}
{/foreach}

 

is not helping, and i do not have any other ideas.

 

And if some of you know how to set custom thumbnail ( i want crop image on my own) in this view, it will be awesome!
