How get the name of currently shown product image for Pinterest

[FluffyCat]

Hi

 

I am trying to add a Pinterest button to my product page. I have added this code in product.tpl:

 

<a href="//pinterest.com/pin/create/button/?url=http%3A%2F%2Fgivensa.com&media={$link->getImageLink($product->link_rewrite, $cover.id_image, 'large_default')}&description={$product->name|escape:'htmlall':'UTF-8'}" data-pin-do="buttonPin" data-pin-config="above" target="_blank"><img src="//assets.pinterest.com/images/pidgets/pin_it_button.png" /></a>

 

This works almost perfectly except for that it does not select the currently showed image but the default one which might not be the one the user wants to pin.

 

Is there any way to modify the getImageLink command above so it selects the product image that is currently shown?

 

Thanks in advance
