Allegedly, on or about 17 August 2016, Patrick O'Callaghan sent:
A way to reorder the pictures in a directory (like a slide show) but
actually assign regular names so they maintain the lexical ordering. I
have a large number of old slides I've scanned and want to re-order
them by their chronological date, but of course they have no
timestamps.
Probably back several releases, gthumb offered a feature useful for
this, but I cannot recall what software I used to do it any more. You
can add EXIF data to pictures that don't have it, letting you write in
the photos real data, rather than a file-creation date, and sort on that
data.
Upon reflection, it may not of have been gthumb, it seems to like
putting metadata in an XML file, rather than in the image. Making it
hard to use the images outside of the gthumb program.
While there's value in having external metadata, it's not convenient for
sending files here and there. You have to hunt down the extra file to
include it, the recipient has to keep both files, and has to have
software that reads the XML file.
