Sort of found a solution but it is not really helping me as I have to rename over 600 scanned images
There is a routine in the right click menu that will AUTO RENAME the selected thumbnails.
You set the parameters of the renaming, and select as many thumbs as you want to do at one sweep, and Qimage will do it for you.
I just tested it, and I renamed a bunch of images to the EXIF date the pictures were taken including Year, Month, Day, Hour, minute and second, if that will help.
Or there are other renaming solutions to choose from if you don't like the EXIF route.
