Image field from product display

That would be a fine addition! Pull Requests are welcome.

Here's a patch that should work! It adds image fields from the chosen node (product display) type.

Then, when building the image_url, looks for the image on the product first; if it's not found there, it will try the display node. This means that you will want to avoid having the same image field machine_name on both your display node types and product entity types.

Whoops, forgot to include the change to the admin form. New patch attached.

@torgosPizza the latest patch is missing

$field_name = variable_get('mailchimp_ecommerce_commerce_image_field', '');

Without it, you'll get a lot of "variable undefined" errors.

Additionally, the following code:

if ($wrapper->__isset($field_name) && $wrapper->{$field_name}->value()) {
  $image = strip_tags($wrapper->{$field_name}->value());
}

Provides the error "Warning: strip_tags() expects parameter 1 to be string, array given".

Changing status to needs work. As it stands the patch does not work.

My attempt at a patch for this issue. Please review.

The above patch didn't work for me. Here is an updated patch.

#9 worked for me as well on version 7.x-1.5. Thanks, @firewaller!

Re-rolled #9 against latest dev.

Looks good, thanks all!
