If you need iPhoto version 9.4.7, which was included in the OSX Mavericks GM release, here's the download link:

Download iPhoto 9.4.7

Do not install if you're not running OSX Mavericks!
There's no version check during installation, so attempting to install on an unsupported OSX version will break iPhoto.
