I have a six-minute audio recording. I want to add slides with Powerpoint or with something that will give me similar results. Each slide needs to appear at a precise time. I would like something free or inexpensive, since I don't contemplate doing this again. I would not like to spend a lot of time learning new software. I'm reasonably good at using Powerpoint, and I have made screencast presentations with Jing. Ultimately the finished produce needs to go on the web.
I found out that Powerpoint had the advantages that (a) I was already familiar with it, and (b) I was able to fill and format the slides with good control. However, monkeying with the timing was rather tedious. Next time I'd like to try something different. Maybe Movie Maker.
