Thanx for the answers.
BTW, I just updated the WooCommerce plugin to v3.0.0 and the image zoom/lightbox not working anymore. Can you guys share with me the theme version that fixed this issue?
If you don’t remember, I believe the version is the same with this top discussion post https://themeforest.net/item/woopress-responsive-ecommerce-wordpress-theme/9751050/comments?page=51
And can I know what files/folders of the release that affect with zoom/lightbox? Only the files inside the woopress/woocommerce folder ?
