Image quality (size (weight file) vs pixels)-reference image

[Recherchiste]

Hello,

When you are in the process of similarity search images, is it could be used as a reference image which has the best quality, or who has the best proportion to its size (weight file) vs pixels, because in fact it is always the best image quality that we want to preserve. Currently, when the reference image is of lower quality than other similar images, we have to go find the file of the reference image in Windows Explorer to delete it because there is no possibility of delete only the reference image in XnView.

Thank you.
