The Happiness of the Katakuris at IMDB
Remember how they called Shawn of the Dead "a romantic comedy with zombies"? Happiness is a Japanese musical with zombies. The cover photo with the Sound of Music line up and a shot from the main zombie dance number superimposed over the sky predates Shawn by several years.
Final thought: but the love interest in Happiness is a con-man
The comp.graphics.misc frequently asked questions list, with answers, about JPEG compression and JFIF files. Last modified in 1999, some of the questions are quite dated, but many are still relevant.
The W3C page on the image/jpeg file format is brief, but it has links to two PDF files documenting the JPEG FIle Format, the standard way to contain images compressed with the JPEG mechanism.
A page I made extolling the virtues of the Portable Video Research Group JPEG implementations. This is an old and obscure tool that I feel needs more recognition.
