kerrin–since I’m now leaning towards the image not having been a puzzle on purpose, but rather a casualty of careless code obfuscation, sure:

As far as “having to install python”, you don’t, of course, it was just my weapon of choice for figuring out what the image was. There seems to be a general consensus that the substitutions identified by my script don’t reveal any great JoCo secrets which would be rewarding (or possible) to find otherwise, so a much faster alternative to the brute-forcing script would be the following (or equivalent):
$ perl -pe ‘s/code/md/g;s/python/pps/g’ joco.b64 | base64 -d > joco_image.png
Where joco.b64 is a text file with the contents of the final comment in the JS source, and the output image is the same as shown at the link above.
