After downloading and extracting the zip archive, copy the Keynote Action Pack to your iWork folder (most likely /Applications/iWork ‘06). In order for the automatic slide titling and automatic QuickTime export to work, you must enable GUI scripting by opening the Universal Access panel in System Preferences. Place a check in the box at the bottom of the window where it says “Enable access for assistive devices.”

To use the Automator Actions from the Finder, copy both workflows to ~/Library/Workflows/Applications/Finder. With that complete, you’re ready to use the actions. Browse to a folder where you have a bunch of image files, select the images you want in your slideshow, then right-click and choose Automator->Create Keynote Slideshow or Automator->Automagic Slideshow.

If you wish to change some of the settings, such as the template used in Keynote or the slideshow resolution, just open up the actions in Automator. I have tested these actions with iWork ‘06 only, so they may not work with earlier versions of Keynote. Let me know how they work for you.
