Show only product with images

[asdf1]

Hi

I search in forum, google, but i don't find...

Does anyone know how I can do so only show products with photos in product-list.tpl

My PrestaShop version is 1.4.6.2

I tried the following {if $product.id_image}

{if isset($products)}
	<!-- Products list -->
	<ul id="product_list" class="clear">
	{foreach from=$products item=product name=products}
	{if $product.id_image}

...............

	{/if}
	{/foreach}
	</ul>
	<!-- /Products list -->
{/if}

but this not work

 

Thank you!

I'm not sure the variable is id_image but can't even check it. What is it using on the image block part?
