contact-sheet is a Python script to turn a big directory full of photos into a bunch of thumbnails and HTML pages. If you have an enormous amount of photos on disk and browsing them is cumbersome, contact-sheet can give you a quick overview of what you have. I wrote it over the course of a few evenings in 2018.
Here's a screen shot to give you a sense of what the output looks like:
