Using Apple TV
Optionally, if you have an Apple TV connected to your HDTV, you can display the images, taken by the workflow, on the television at the same time you display them on the computer.
Launch iTunes on the computer you use to sync with the Apple TV. Select the Apple TV in the list of sources on the left of the iTunes window. Click the tab for Photos and set the source for the photos to be the Party Pix folder you created as the destination for the video snapshots.
Using the Apple TV remote control, select Photos category.
Next, select the Party Pix folder to begin the slideshow.
Party-goers can view the images and add more as the party continues.
