I can't say just at the minute exactly how many images are on the National Disc. One day I hope to be able to bring you this information, unless somebody else works it out first.
There are 54,000 frames, everybody knows that, but they aren't all still pictures. Some are the starting video, some are the help video, some are test frames, some are blank and some are index frames. The rest are still pictures depicting life in the 1980s.
Even so, this means that there is almost limitless opportunity to put together your own montage of images, and using the video mixing facilities of the Domesday Player, overlay your own captions.
That's what this does, using images of the 4 Doctors I found.
