You need to edit the "shopping cart form" view. If your image field is on the actual product then go to advanced and add the relationship "(Line Item) Commerce Line item: Product". Then go over to fields and add your image. Make sure you have some image styles defined because you'll probably want a smaller thumbnail there.

If you also want this to happen on the checkout page when confirming the order do the same thing to the "Shopping cart summary" view.

I think you're right. It doesn't seem like a security issue. I'm going with along with that, and allowing that permission. Mine's a testing site anyway, so it's no risk while this issue gets wrangled out, or patched. And no, I don't think you want any patch created by me; it would probably crash the whole Commerce project.

Anyone else who, like me, had the product image in the product display node rather than the in the product itself, you can get this to display in the checkout views using multiple relationships as described here - http://www.apsinfrastructure.co.uk/blog/drupal-commerce-cart-node-fields

so, (taken from the above link):

1. Add a relationship 'Commerce Line item: Referenced product'
2. Add a second relationship 'Commerce Product: Node referencing products from [field_name]' where [field_name] is the machine name of the field in your node that references the product itself
3. If you have multiple product display content types, repeat step 2 for each
4. You can then add fields from your product display nodes

I am handling the display of my products in the cart using the "products in cart" display within my variation type. This display the image is set to "product_thumbnail" and the cart view has the field "commerce line item: product" with the view mode set to the "products in cart". This seems to be all handle well with the kickstart installation and the existing variants (when they are added to cart), but new product variants I have created dont show the images when added to cart (or add to cart confirmation) even though they have the exact same display setup.

Just in case somebody needs to do this using Kickstart

1) If you use more than one product display, make sure to re-use the same image field on all product displays
2) Set up an image style e.g. product_image_cart
3) Go to shopping cart, use contextual link to "edit view"

and follow most of dilari's steps above

4) Add a relationship 'Commerce Line item: Referenced product'
5) Add a second relationship '(Product) Commerce Product: Node referencing products from field_product' (in Kickstart that works for all product displays)
6) Add field '(Node referencing products from field_product) Content: ', assign image style, reshuffle order

Done.

I hope this makes sense :).

I have a situation where the product image is handled by the product display node, rather than the variation. Consequently, I am not able to view a product image in either the cart confirmation view or the cart view.

When I try to modify the the cart views, I find that they do not appear to allow a relationship with the referenced content type, from where I could locate the image field.

Am I missing a trick here?

Well, it appears the best solution is to probably add the image field/s to the Product Variation and not the display node.

I think that depends on what and how you are selling. Both methods have their pros and cons

I have a product, a content type to show it (product_ct). product_ct has the field Icon (image). What I need is to show that icon in the /cart page.... (shopping cart) , any ideas?
