I suppose that you could use a demo maker program or some multimedia presentation software like Scala MM400. Both of them should let you combine images, text, wipes and effects with music and sound. Here are some links to some software that might help, sorry I haven't tested any of it yet:
The RSI Demo Maker was discussed in an earlier thread, perhaps you can still find it in the Zone section of the EAB file server : http://eab.abime.net/showthread.php?t=14922&page=2
I don't know where you might find Scala MM400 but it's probably the best multimedia presentation software for classic Amigas. Perhaps other people can suggest alternative software you could use to make your own audio-visual presentation.
