How to make product image on product page open product link.

I was also looking to do this. I’ve copied the template directory to my theme but the product-image.php file does not have the line of code you mention.

Change the line:
$image_link = wp_get_attachment_url( get_post_thumbnail_id() );
to
$image_link = esc_url( $product->get_product_url() ); Save and enjoy.

Here’s my file code:

<?php
/**
* Single Product Image
*
* This template can be overridden by copying it to yourtheme/woocommerce/single-product/product-image.php.
*
* HOWEVER, on occasion WooCommerce will need to update template files and you
* (the theme developer) will need to copy the new files to your theme to
* maintain compatibility. We try to do this as little as possible, but it does
* happen. When this occurs the version of the template file will be bumped and
* the readme will list any important changes.
*
* @see https://docs.woocommerce.com/document/template-structure/
* @author WooThemes
* @package WooCommerce/Templates
* @version 2.6.3
*/

if ( ! defined( ‘ABSPATH’ ) ) {
exit;
}

global $post, $product;
?>
<div class=”images”>
<?php
if ( has_post_thumbnail() ) {
$attachment_count = count( $product->get_gallery_attachment_ids() );
$gallery = $attachment_count > 0 ? ‘[product-gallery]’ : ”;
$props = wc_get_product_attachment_props( get_post_thumbnail_id(), $post );
$image = get_the_post_thumbnail( $post->ID, apply_filters( ‘single_product_large_thumbnail_size’, ‘shop_single’ ), array(
‘title’ => $props[‘title’],
‘alt’ => $props[‘alt’],
) );
echo apply_filters(
‘woocommerce_single_product_image_html’,
sprintf(
‘%s‘,
esc_url( $props[‘url’] ),
esc_attr( $props[‘caption’] ),
$gallery,
$image
),
$post->ID
);
} else {
echo apply_filters( ‘woocommerce_single_product_image_html’, sprintf( ‘‘, wc_placeholder_img_src(), __( ‘Placeholder’, ‘woocommerce’ ) ), $post->ID );
}

do_action( ‘woocommerce_product_thumbnails’ );
?>
</div>

Anyone know how I should modify this?

Cheers
