Tired of using just 12 photo frames? I read an article in Macworld (March 2008) that referred to this link: macworld.com/3330 Simply put, instead of the usual 12, you can now have access to 72 photo frames! According to the author, "For some reason, [other than the 12 frames,] Apple decided to embed quite a few more frames (and even use them in their included themes), but not show them to the user. If you crack open the Keynote app and drill down through the Frameworks folder, you’ll see all 72 frames. Here's a screenshot of his photo frames menu: For the entire procedure, please click on the link above. Warning: The procedure involves replacing certain files. If you're not too sure of what you're doing, don't proceed. The author has this reminder before proceeding: "Oh, make sure you keep a fresh copy of the app around just in case you break something."
