This both looks and sounds very interesting. Not only that but it is currently freeware.
What is iPhoto Buddy?
Buddy is a Mac OS X application (Universal) that allows you to easily
create, manage, and switch between multiple iPhoto Libraries. The
advantages of splitting your One Huge Photo Library into multiple,
smaller ones include improved iPhoto performance, increased flexibility
in organizing your digital photo collection, and a consistency with
most other Mac applications that allow their respective data to be
stored in as many documents (in this case, "Libraries") as you like.
Buddy uses a simple, streamlined interface that was inspired by iPhoto
itself. Anyone that has used iPhoto will immediately feel right at home
using iPhoto Buddy. It truly is a companion application–a real buddy!
iPhoto Buddy will never alter/move/delete your Libraries or your photo files. It’s perfectly safe!
What can you do with it?
iPhoto Buddy, you can easily manage an entire list of iPhoto Libraries,
enabling you to quickly and easily open the Library of your choice for
viewing/editing/printing in iPhoto. You can easily switch between your
multiple Libraries, and iPhoto Buddy will automatically quit iPhoto and
instantly re-launch it with the newly selected Library (iPhoto can only
have one Library open at a time). There is no limit to the number of
Libraries, and they can be located in various locations–even on
external hard disk drives, network volumes, or encrypted disk images.
Each Library can be assigned its own name that differs from its folder
name in the Finder; each Library can be assigned a thumbnail image that
can help to remind you of its contents; and each Library can be
password protected for privacy/security.
iPhoto Buddy also
displays various details about your Libraries without launching iPhoto.
Information like each Library’s size and image count as well as a
complete listing of the Albums, Smart Albums, Folders, Books, Slide
Shows, etc. contained therein.
And in keeping with the enhanced
integration of the iApps that Apple introduced with the original iLife
package, iPhoto Buddy also allows you to open iMovie, iDVD, and iWeb
using any of your iPhoto Libraries for importing photos into your
Movies, DVDs and websites. In fact with iPhoto Buddy, any application
that contains a Media Browser for accessing your iPhoto Library, can
used with ANY of your iPhoto Libraries.
