Could be an interesting avenue to explore though, I'll have to see if it can read my files, particularly that tricky audio track...

So you wouldn't even have to write anything if you were being lazy. It also shows you how to interface between the JPEGs underneath and how to get at them, it shows that there is a header that describes the motion-ness of the set of JPEGs to come (= a pseudo folder). See: "A JPEG movie file consists of a header followed by a sequence of JPEG-compressed images followed by one or more sound tracks. It responds to a subset of the protocol for MPEGFile so that a JPEG movie can be played by MPEGDisplayMorph as if it were an MPEG movie. " cf: Browser:: Movies-Kernel :: JPEGMovieFile Hi Ron,
