When light table view is active rigth click on an image (main or in film strip)
In context menue you find “Pfad kopieren” (maybe in english it’s Copy location)
(I’m not sure whether an image must have a GPS info to show this option in context menue)
After having copied you’ll find “Ort einfügen” (Paste location) in context menue
In my understanding “Pfad kopieren” means “copy finder path to image” but it’s copy the GPS location information of the image
