In your style CSS, paste this CSS:

.woocommerce-product-gallery { opacity: 1 !important }

This will work for sure and if you want gallery slider, lightbox and zoom then paste this code into functions.php
/*adding product lightbox and slider*/
add_action( 'after_setup_theme', 'deb_theme_setup' );
function deb_theme_setup() {
add_theme_support( 'wc-product-gallery-zoom' );
add_theme_support( 'wc-product-gallery-lightbox' );
add_theme_support( 'wc-product-gallery-slider' );
}
