The thumbnails don't belong to the photos, how do I fix it?
My iPhoto library shows one photo in the thumbnail (distorted) and opens another one. In other words, my thumbnails are corrupted. What should I do to fix that??
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to rebuild the thumbnails. It can take 3 or 4 goes for this to work
