Overrides: –

What happens when you disable the Genesis Connect for WooCommerce plugin? Does that improve things?

The image is added via the ‘woocommerce_before_single_product_summary’ action. This action is in the plugin (templates/single-product.php).

Maybe Magazine Pro or your customizations have removed this action.
