mac iphoto - setting the library location

from http://www.macosxhints.com/article.php?story=20020107231049966

iPhoto has a default that can be used to change the location of the photo library in a fashion similar to the way iTunes can change the location of the music library.

For iPhoto, this is of critical importance in that any image added to iPhoto is copied into the library (unlike iTunes, which simply stores a pointer to the original file). Considering what can be done with an image in the library, this makes a lot of sense -- it will make more sense once Apple supports multiple libraries in a more traditional multi-document application approach.

To change the default file store location, go to terminal and type:

  defaults write com.apple.iPhoto RootDirectory /path/to/desired/location

To remove the change default:

  defaults remove com.apple.iPhoto RootDirectory
