The best way to consolidate two iPhoto libraries into one library

iphotolibrary-managementsnow leopard

On the family's iMac my wife and daughter have separate user accounts, each with their own iPhoto library. My wife has asked me to consolidate both libraries into a single library for convenience.

What is the best way to do this? Can it be done with the existing software and utilities that come with Snow Leopard or is there a 3rd party utility that facilitates the process?

Thanks in advance.
