iPhoto: EDIT IN PHOTOSHOP WITHOUT SETTING PREFS

Earlier, I showed how to set up iPhoto to let you edit your photos in a separate image-editing application (such as Photoshop) by changing your iPhoto Preferences. But here's a great tip if you only occasionally want to edit your photos in a separate applicationjust drag the thumbnail of your photo right from the iPhoto window onto the Photoshop icon in the Dock. Your image will be opened in Photoshop (or, of course, you can drag it to any other image-editing program just as easily, but really, why would you?).
