Turn your digital color photographs of people into a contrasty grayscale which is friendly to flesh tones with GIMP and this pygimp gallery making script collection.
These scripts un-archive into .gimp-2.3/plug-ins/ and the gallery plug-in should be found in the gimp menus at <Toolbox>Xtns/Effected Gallery/Salubriated Landscapes. Show the directory which contains the images and what kind of image to look for (JPEG, PNG or XCF). Next show it where you would like the plug-in to save the new images and the html at.
An example of the images and web pages can be seen in my Norwegian Vacation Photographs.
