stop resize button for wordpress media

That’s a bit tricky because WordPress doesn’t offer this functionality out of the box. But a workaround would be to stop WordPress from generating additional image sizes for uploaded images. But it will apply to all image uploads, not just those in the WooCommerce product gallery. If you wanted to try it out, here’s the code for that:

function disable_image_sizes($sizes) {
    unset($sizes['thumbnail']);
    unset($sizes['medium']);
    unset($sizes['large']);
    unset($sizes['medium_large']);
    unset($sizes['1536x1536']);
    unset($sizes['2048x2048']);
    // Add any additional sizes you want to remove
    return $sizes;
}
add_filter('intermediate_image_sizes_advanced', 'disable_image_sizes');
