How to get url of Product image field of Entity Reference field
As you're creating your view, you need one more relationship. Look for this relationship:


  Commerce Product: Referencing Node
  
  (Relate a product to the Node referencing it through field_product.)


This will allow you to harness the "reverse-relationship" going from the product to the reverse-node. Add this relationship, require it, and then use this to generate your links.
