I've had this script (from the HnH forum I believe, is where I got it?) and it does work fairly well. I'd just ended up prefering the Photoshop script because it lets me compress the images before chop chop, lol. I also don't know the Python language, to tweak this with at all. Something new to learn in the future.
Do note, if you use the Python script: You must use Python 2.x, 3.x does not work with this. 2.7 worked fine, though. Unless, of course, you know the Python language and can convert it over. Mentioning this because the Python page download link sends you to version 3.x.
That aside, I just realized that I posted the Photoshop script I use, and the HTML/JS, in a separate thread, so here is a link:
