Having trouble loading the parent link so here's my own version for anyone else with the same problem:

I had this master plan of putting it into a webpage and using some sort of screen-print extension or JS to save it as one huge image. But as of now I've now spent more time on the capture part of it than I did on the initial scripts to grab the files and render them out in JavaScript, and need to get back to work instead.

If this helps anyone get closer to a full image, please post the result!
