Duplicated featured image in product gallery

Hello, i apreciate very much this fantastic plugin but i am facing a little issue.
The featured image is being repeated in the product gallery that is shown under the first image of the product. This is not a problem for the products that have more than two photos but for the ones that have oly one photo it looks a little bit messy for me. Is it possible to remove the first image in the product gallery only for the products that have only one image?
Thank you!
