On an image right mouse click for context menu and select Copy Image Location (this for Firefox, other browsers, other names) which copies the location URI into the clipboard. Paste somewhere else (in an editor or even the URL bar of another browser tab) and you see either .../galleries/... or .../upload/... directory under which the image is located.

For albums it depends, for virtual albums there's no location at all, for physical albums the path is present in the image URL.
