i messed around with glitching jpgs a while back. i started by just manually editing the text info, but then just wrote some php and processing apps that subtly randomized the byte info and saved the manipulated images. then i filtered the difference between the two text files to see where the changes were. it was still far from meaningful, but creating a basic app to do your dirty work for you is a much more rapid way of finding out what text corresponds to which part of an image in an image text file.
- i only used php bc it was a dynamic app that scraped images from the web. i'd recommend using processing.armsbottomer
