Finally, here’s a handful of general—although perfectly terrifying—troubles.
If the program “unexpectedly quits,” well, that’s life. It happens. This is Mac OS X, though, so you can generally open the program right back up again and pick up where you left off.
If the flakiness is becoming really severe, try logging out (choose → Log Out) and logging back in again. And if the problem persists, see the data-purging steps on the next page.
Installing more memory is by far the best solution to this problem. iPhoto loves RAM like Paris Hilton loves attention.
For an immediate (and less expensive) fix, keep your Photo Library a reasonable size and collapse your film rolls (page 104).
Chapter 9 covers network photo sharing in detail. If you’re having trouble making it work, here’s your checklist:
Make sure you’ve turned on “Look for shared photos” in the Sharing pane of iPhoto Preferences.
Is the Mac that’s sharing the photos turned on and awake? Is iPhoto running on it, and does it have photo sharing turned on? Is it on the same network subnet (network branch)?
Do the photo-sharing Macs have iPhoto 4 or later installed?
Double-click its name, and then type in the new label.
