I just looked at a thread about iPhoto copying images and it got me thinking about how I organize my own photos. I use both the Finder and iPhoto to look for and view photos, and so I ended up having two copies of each photo - one for the Finder, and one within iPhoto. This is pretty annoying, but I always thought that iPhoto needed its own copies so that was that. However, I just discovered the "Copy Photos to the iPhoto Library" option under the Advanced Preferences pane. (duh). If I uncheck that, can I just have iPhoto refer to the photo's original location (a Pictures folder within the Finder) instead of having two copies of each picture on my hard drive? Like, how iTunes does it if you hold down the Option key when importing a song...
