I have been looking for a setting to display the file path of a photo displayed in Thumbnail view. I see that it's possible to show an image in the native file manager, but I was hoping there was some way to display this information in the default digiKam display window.

Thanks.

See if that's what you're looking for. The words I have written here are in German, you will surely find your way.
