PhotoPeach is a very easy to use slide show maker tool. You can import photos from picassa, Facebook (or upload from your computer). Arrange the order of photos and then add captions to each. Then select music from library (or search for music from YouTube videos).

When published, PhotoPeach automatically creates Ken Burns like pan and zoom effects. When published, you can also post to Facebook or twitter. If you upgrade to the pro version, you can download video versions of your slideshow and you can also upload your own mp3 audio for use in slide shows.
