How (not) to make a slideshow in iPhoto

As you can see in this tutorial on Apple's site, you can quickly view photos in a slide show with the button at the bottom of the window. You can set the order, pick a theme, add music, transitions, etc. But don't get too far because you can only play that slideshow on your computer, you can't publish or covert it to video (unless you use a screen recording program).

In the same tutorial, you can see there is also a Slideshow Project you can create which can be exported. The only downside is the way you have to arrange photos is a small strip at the top of the project window rather than a proper iPhoto album.

So the lesson learned is if you plan to publish a slideshow, make a project, don't do one on the fly.
