Hi,
The product image slideshow HTML is powered by WooCommerce, not the theme. Editing the template files is the wrong method, you will want to override the functions we have in our framework using a child theme.
You can also hook into the supplied actions seen throughout the template files with your own functions.
Knowing this, in the file content-single-product.php
you will find the action woocommerce_before_single_product_summary
. This is located after the main product image.
You can then hook into that action to add your own content via your own custom function which you would add to your child theme functions.php
file.
Thanks.
