Hi,
Many websites selling fashion have a sample material (not just plain color) like http://us.levi.com/product/index.jsp?productId=13075533&&cp=3146842.4305630.2765287
I think we should include the ability to crop an image from the product picture and save it as product attribute specification.
please vote for it at
