Change image behavior on Product Admin Controller Column

[mlizana]

Hi! I want to change the behavior of this code in AdminProductsController:

        $this->fields_list['image'] = array(
            'title' => $this->l('Image'),
            'align' => 'center',
            'image' => 'p',
            'orderby' => false,
            'filter' => false,
            'search' => false
        );

To point to my custom URL (not using product ID's), something like:

 

'image' => '/localhost/images/products/product423.png"

 

Any ideas? Thanks!
