Woocommerce product

You guys doing pretty good job with woocommerce “simple product”, but not so much with “external product” (I know, it’s rarely use). On this page

the image doesn’t have a link.

I just want a link to a product just like the button.
————————————————————————————–
add_action(‘woocommerce_after_shop_loop_item’,’replace_add_to_cart’);
function replace_add_to_cart() {
global $product;
$link = $product->get_permalink();
echo do_shortcode(‘[button border_radius=”10″ three_d=”no” size=”small” color=”belize” title=”More Info” link=”‘.esc_attr($link).'”]’);
}
—————————————————————————————-

thank you guys
