different apperance in product-list.tpl when no image available

[MrPaul]

Hello, can anybody help me

 

I want to modify the appearance of a product in category lisitings, mainly the product-list.tpl in presta 1.5.6.1.

 

When there is no image available, so just the product name and short description shall appear, WITHOUT the image box saying "no image available".

 

So I need to find out , if a product has no image

 

I tried :

 

{if $product.id_image == 0}

{if $product.id_image == NULL}

 

nothing works

 

How can I see, that a product has no image available?
