+@c ***** Displaying images not generated by lilypond-book *****
+
+@c Current installation setup of Info docs requires that all images are
+@c expected to be found in the `lilypond/' subdirectory. `lilypond-book'
+@c already generates proper @image commands for images of music; these
+@c macro definitions do the same for other images.
