I have a view of product displays (content types) with a field "rendered node".
The configuration of this field is "Show complete entity" and a special display mode of my product display type (content type).

The reason why I use the field "rendered Node" is that - as far as I found out - this is THE ONLY WAY the selection of product variants is shown correctly (e.g. no problem with multiple values).

Now I want to show some product displays with their referenced product variants.
Everything seems to be fine - except the images of the products: they show up in the same size as configured in the standard display mode of the product type´s display settings (the product type´s, NOT the content type´s).
In the display settings of the content type I have no choice of switching the product imge´s display format - it says that I have to configure it via the display settings of the product type. OK.

What I want to achieve (and already almost completely did) with this view is:
- show some fields of the product display (content type) - e.g. title, description
- let the user select the product variations (I use Commerce Fancy Attributes for choosing the color)
- show some fields of the products (variations)
- have a different (smaller) sized product image then in the node´s full-view mode

Just to clarify:I already got this view with all the product fields showing within the rendered node.
The only thing I need is another display format of the product image.

Or should I go another way?

Thanks!
