I archive my digital photos and documents according to their provenance (organized by source, etc), but I need to arrange these items by locality, families, subjects, etc. without duplicating the original images.  So I create shortcuts for the images and I then move and duplicate the shortcuts as needed to arrange them for display.  This allows images to be linked to one or more contexts without duplicating or moving the originals.

Unfortunately, the Photo Gallery extension which allows editing and tagging in images cannot work with the shortcuts.  I must manually locate and work on the originals, which is a much more tedious process when working from the display context.  This Photo Gallery extension needs be able to find and open the original image from its shortcut, to streamline this process.
