Remove zoom effect on WooCommerce product image

Can you try this instead?:

function remove_image_zoom_support() {
    remove_theme_support( 'wc-product-gallery-zoom' );
}
add_action( 'wp', 'remove_image_zoom_support', 100 );

Wow, that was quick!
Works perfectly, thanks a lot!

You're welcome :)

Where would I paste this code to disable the zoom over hover effect?

I used a slightly different code, also disabling the lightbox, however, when clicking the image, it is directed to its larger variant, in full screen (with this, leaving the site).
Is it also possible to disable the click completely?

function remove_image_zoom_support() {
    remove_theme_support( 'wc-product-gallery-zoom' );
    remove_theme_support( 'wc-product-gallery-lightbox' );
}
add_action( 'wp', 'remove_image_zoom_support', 100 );

Hello Tom.

This code has been deprecated since the release of WooCommerce version 3.0+.
Now the code that works is this, however, only if you have a single image for the product.

function custom_single_product_image_html( $html, $post_id ) {
    $post_thumbnail_id = get_post_thumbnail_id( $post_id );
    return get_the_post_thumbnail( $post_thumbnail_id, apply_filters( 'single_product_large_thumbnail_size', 'shop_single' ) );
}
add_filter('woocommerce_single_product_image_thumbnail_html', 'custom_single_product_image_html', 10, 2);

But in my case, as have a gallery of images, I solved with CSS (and without the code above):

.woocommerce-product-gallery__image.flex-active-slide {
    pointer-events: none !important;
}

Sorry to put the options here, but maybe I can help other people. :)

Thank you! I appreciate you sharing the solution :)

Thank you a lot!
I was using "after_setup_theme" and it was driving me crazy!

Glad you figured out :)

I was searching for the same code. Thank you Tom.

works perfectly. thanks! ;)

Glad you found the post :)
