I've been searching for hints as to how to fix a photo sync problem for my iPhone 4, but to no avail. If anyone has heard of something like this happening, please help! I use iPhoto'11 (9.1.3) to organize pictures that I want to sync with my iPhone. The problem is that when I go into iTunes (10.2.2) to select which photos to sync with my iPhone, some of the Events have missing photos. One Event, for example, has 40 photos in it, as evidenced in iPhoto, but iTunes shows the Event having zero photos. In another Event, which has 55 photos, iTunes sees 2. In other Events, iTunes sees all of the photos. Everything iTunes sees is synced fine with the iPhone. There appears to be plenty of space left on the iPhone (2.5 gigs). One factor might be a recent upgrade to iPhoto'11 several weeks ago. Events made and synced before the date of the upgrade appear to all be fine. After the upgrade, iTunes sees some Events as empty of photos, some Events with only a couple photos out of many, and one Event with all of the photos. Also affected are new Faces that were added after the upgrade. Although some of those people are in photos that were synced, their names are missing from the Faces list in iTunes and on the iPhone. I'm not sure if this problem started at exactly the same time of the upgrade or later, though. Does anyone have any insight into this? Any help would be greatly appreciated!
