Perl script
for Unix systems which uses Netpbm and JPEG utilities
to prepare an HTML document containing a graphical
index for a collection of image files, with each small thumbnail
image linked to the corresponding full-size image.
Update: Version 1.1 (July 2004) fixes compatibility
with current releases of image processing utilities,
adds support for PNG image format, permits specification of
the title of the HTML image document, and allows opening
images in an auxiliary browser window.
