Try rebuilding your iPhoto Library. When attempting to rebuild your Library, it is a good idea to create a backup of the iPhoto Library file, should an unexpected error not allow the rebuilding process to complete properly.

1. Press and hold the Option and Command keys and click to open iPhoto.
2. When the rebuild iPhoto Library dialog box shows, select the options that apply to your particular issues. Do not select boxes that do not apply.
3. Click repair and check the results when iPhoto reopens.
