Reply To: Variation products, dosnt show image gallery for variations

Try to add the following PHP code snippet to the child theme functions.php file to fix this

function wd_wc_ajax_variation_threshold( $qty, $product ) {
    return 100;
}

add_filter( 'woocommerce_ajax_variation_threshold', 'wd_wc_ajax_variation_threshold', 10, 2 );
