Image - sort order

RSmith

I have my galleries sorted by Filenames. When I create a copy of an image, the images randomly sort themselves between the two duplicate images. I want to always sort in a specific order, usually the edited image 2nd after the original. Is there some way to make this happen? I know that I could download the edited file, rename it so that it will stay 2nd, and upload it back to the gallery, but there should be a way to do it in the gallery.

Does anyone have any solutions for this?
