thumbnail_index - make an HTML index file for a bunch of images

Fetch the software.

Run this script in a web directory consisting of all or mostly image files. It'll create an index.html of thumbnail images, putting the thumbnail files in a hidden subdirectory.

It avoids unnecessary work by comparing the dates on already existing thumbnail files and not re-creating them if the corresponding original has not changed.

It also refuses to overwrite an index.html file not created by this script.

Here's a sample.
