I wrote a shell script that creates a html (web page) index of a
directory full of jpeg images. Requires ImageMagick.org and bash or ksh
to run. The output is similar to the
Ireland web pages referred to by the next
two links. This script uses html 4.01 and Cascading Style Sheets.
Thumbnail images are created by the convert program that is part of
ImageMagick. In the resulting web page, one may click on the thumbnail or
on the file name to view the image. The script works fine under Unix or Linux,
but may need to be changed to run under windows.
