magmi image processor imports remote images, even if they don't exist!
In the following example, image-03.jpg does not exist on the remote server. But the image processor, creates a blank record under Product Information > Images. It imports image.jpg, image-01.jpg, image-02.jpg and creates (assigns) a 4th blank record.
I don't think it makes any difference, but I am using Bundle Item processor v1.1 as well.
