Vending Machine-less Lounge:: Mac OS X Panther: iPhoto: Change Default Photo Program
If you have used iPhoto in the past and have set it to be the default program to start when you connect a digital camera to your computer but now have opted for a different photo organizing software, you may reset your default photo program in the following manner.
iPhoto uses the small application “ImageCapture” to load pics from the camera. Open “/Applications/ImageCapture” and go to the application menu -> Preferences. There is a pull down menu to change your default photo software.
