Aha. Well, if the images are being generated by some other program
(like say JPEGs from PhotoShop) you are probably SOL.
HOWever.
Apparently with QuickTime 5 and later you can append some kind of
special block or stream identifier to a movie, preventing it being
opened in any but very specific situations. This might be exactly
what you need. You'd have to check out Apple's docs for more, but it
might not be too wild to make a 1-frame QT movie that has that
protection built into it, thus allowing your client to use a standard
format that just doesn't happen to be readable in anything but his
proprietary software.
Another advantage of that is QT is direct to stage, and generally
screenshots/screencaps will not grab the QT frame -- you just get a
black rectangle instead of the image.
If that's not an option either, well, how is the client planning to
*save* the files that you're trying to import?
