Scrapping 4 ecom

Hello, I have 2 problem when trying to scrap a shopify store : 1st - I'm not able to scrap the product gallery after following your tutorial 2nd - How can I add the variation settings like Size or color from the product ? -- Another question - it is possible to rename image name ?   For privacy I prefers to not share the link of the website I want to scrap but I can't send it to private message.
