FlexSlider/WooCommerce Single Product Image Gallery: Trying to trigger featured image change from the color picker

FYI, I figured out the solution -- I added this code to my theme's functions.php file, and the problem was solved:

function my_product_carousel_options($options) {
  $options['controlNav'] = false;
  return $options;
}
add_filter("woocommerce_single_product_carousel_options", "my_product_carousel_options", 10);
