Apple has corrected an issue in iPhoto 4 that caused problems with creating iPhoto books in Europe.

The 4.0.2 updates also addresses "minor issues" with Smart Albums, a new feature in iPhoto 4 that enables users to create albums according to set criteria, just like Smart Playlists in iTunes.

The update will also enable iPhoto to notify users when new versions and updates are available.

iPhoto 4 requires Mac OS X 10.2.6 or later, although Mac OS X 10.2.8 is recommended due to its CD and DVD burning capabilities. The update, available from Apple's Web site or through Software Update, is 5.9MB.

iPhoto is Apple's all-in-one application for importing, organizing, editing and sharing digital photos. iPhoto 4 is only available as part of the iLife package which costs £40 and also includes GarageBand, iMovie, iDVD, and iTunes. The update will not work with older versions of iPhoto, which was previously available for free to Mac users.
