Getting image for product in Cart Screen Really struggling with this (perhaps my brain is tired), but how would I get the image of a product for each entry in the cart screen in Craft Commerce?
This actually depends where the image is stored - if the asset (image) field is on the product, and is called myImage, then as per Brad's example you'd use: 

lineitem.purchasable.product.myImage 

...BUT if it's in rather a field on the variant you would instead reference it as:

lineitem.purchasable.myImage

(This is because lineitem refers to a variant....in the case of a product without variants it references the implicitly created defaultVariant).
