iPhoto Tip Number #9,789

If your iPhoto seems to be malfunctioning - thumbnails missing, sluggish performance when scrolling etc etc, try this little tip out courtesy of Apple's Support.

Hold down command + option when clicking on the iPhoto application. This will bring up a menu where you can rebuild the icons, database or just the whole library.

If you've been manually deleting files in your iPhoto folder to get it to rebuild the library, then this tip is going to be schweet~
