How to change productpage/category view (thumbnail to open lightbox)

Usually product page categories thumbnail opens specific product page but I want it to open lightbox (as it does in specific product page). How do I skip specific product page?

https://www.and1.ee/products-page/jalatsid/ are all products with thumbnails – I want these thumbnails open big picture of the product not product page itself (https://www.and1.ee/products-page/jalatsid/total-assist-mid-2/).

hope you understood ??
