Manage displays of Product:image field directly in Product Display? I have a "Product Display" node showing a "Product" (powered by the Drupal Commerce module).

I have installed the Display Suite module, and created a new view mode for the "Product Display" content type.

The problem is that this new mode is associated with the default view mode of "Product," and I see no way to change this.

What I need is to create a new mode for "Product" and get the view mode of "Product Display" associated with this new one.

Is there anyway to do it?
Go to the Manage Display tab of your product entity and enable the same "View Mode" you use at "Product Display". Do it in the "Custom display settings" fieldset. 

Then set up image style for the Image field. And see changes at the "Product display" page
