How can I filter only the first image of each product?

Our Bulk Image Edit app has an image filter designed to do exactly that! It’s called image position of a product is, and it can be used to target anything from the 1st image (cover) to the 30th image, or the last or 2nd last image. This is often used to target only the product cover, since this image is used to generate thumbnails.

Please see the image below to see where this filter is located.
