Mac OS X Tiger includes a cool slideshow feature in the Finder. This feature is also in Preview, and a similar one exists in iPhoto. You just grab a folder of images, and hit the Slideshow button. Easy as pie.
Except if you want to display the slideshow on a second monitor (like a projector). No dice. Not one of the built-in quick-slideshow features in Mac OS X will do that, even if you put the app on the second monitor and invoke the slideshow. Even iPhoto will let you configure options for a slideshow, but it won’t let you choose the display on which it should appear.
Seriously, how hard would it be to add this feature? Why have no shareware/freeware apps stepped up to the plate?
I finally remembered I could set the other display’s desktop picture to cycle through a folder of images. But it shouldn’t really be that kludgy.
Apple must just want you to buy Keynote.

Hi Daniel
This drives me mad! I have a 24″ widescreen Dell as my second monitor, and using Arrangement to make it the primary monitor, I can read PDF documents and books (typically portrait docs) beautifully. However I prefer to keep the 17″ iMac the Dell is plugged into as the primary monitor. Very frustrating we can’t ’swap’ the slideshow to the ’secondary’ display. Maybe some sort of prefences.list type hack?
Regards
Ivan
