Finding missing photos in iPhoto
Excerpted from iPhoto 08 for Mac OS X: Visual QuickStart Guide by Adam C. Engst
If other iApps can't see your photos, or if some iPhoto albums or photos are missing, quit all the iApps, drag the file "AlbumData.xml" from the iPhoto Library to the desktop, launch iPhoto, create a new album, quit iPhoto, and try the other programs again. Your missing items should reappear.Spotted in the emailing "Mac Tip of the Week" by Peachpit (Mac book publishers).
