I was also impressed that you worked it out. After creating the charts in IDL I use ImageMagick to create custom metadata in my PNG files for display on a website. The images can change as often as daily or as seldom as yearly but must be displayed using static HTML so the dates the data is valid for (or any value that changes) cannot be in the file names. I need to know if something didn't update. With thousands of images I could not expect to visually confirm that all files are up to date. Now a couple of scripts and a program let me know if anything is out of date or missing.
