Hi Al, Thanks for your post. Actually I was aware of this facility however I would like to use several audio files and have some of them go together with a certain set of images. As far as I can see the only way to achieve this is by using another program and 'stitching' all the audio files into one big soundtrack and then use this option. The problem here is that you have no correlation between these programs and you have to compute when the transitions will occur and hope for the best. I would like to circumvent this trial and error way of working. What I also noticed is, when run on different computers, the music and the slides tend to off sync (so not using the option you proposed here). Best regards, Bart
