With Picasa, you can create a slide show and add music. I think it’s a free download.
A few years ago, the music director of our church presented a slide show about a concert tour the choir had just completed. He created the show using Pro Show Gold to organize the digital photos he had taken. This program costs around $40.
I don’t like ordinary-person presentations with music added. Just one slide after another, please. Narration by the author is good. Captions are good. I use an editor to put captions within the jpeg files so they’re there no matter what means of displaying I use (Shutterfly, Nero, etc).
Speaking of Nero, I swear it loses a little resolution when it displays my pictures. I’ve never found good documentation for Nero MediaHome.
