Hi you,
#1. Replace the cards image on the single product page:
Please go to Admin dashboard -> Appearance -> Customize -> Woocommerce -> Single Product -> Single extra description -> Edit your image: https://ibb.co/MngxvDc
Looks like you’ve already changed this photo
#2. Change image shop page:
Please go to https://shobkichuu.com/wp-admin/post.php?post=7851&action=elementor# -> Click Edit section -> Tab style -> Edit background image: https://ibb.co/m8v9YnD
I see you have already changed this picture
#3. We don’t support image background for each product category, if you want to we will charge a custom fee for this request
