The nearest thing you will find are scripts to cut and save a image
along guides (teh ones you drag from the rulers on the sides of the
image).
The "guillotine" plug-in just chops a image along the lines, creating
various open images in teh GIMP - you then have to save them by hand.
However, both the PERL-FU and PYTHON-FU extensions have plug-ins that
will both cut along the lines _and_ save an image to disk as part of
an HTML table (the image files are separate.
The matter is, none of this is available for windows. (Python-fu is,
but hjust for the development version of the GIMP - 2.3.6 and newer)
