Another company that produces slide shows with audio ability is Animoto. While it does cost to make full length videos, you can try it out for free by making 30sec shorts like I did.
For some reason, I was unable to get it to view simply by embedding the actual Animoto video, so I tried uploading to YouTube instead (which, sadly, degraded the quality) which I was able to embed.
However, if you still would like to see the original (and much better quality) version, please click here.
