It's got some cool organizational features (and some really stupid interface errors) but it's not worth it by a long shot. :-( And in Apple's ongoing efforts to out-Microsoft Microsoft, the program is called "iPhoto 08" and is part of "iLife 08" but is actually iPhoto 7.
EDIT: ConnectedFlow has released an updated version of the Flickr exporter. You must remove all previous versions of the plugin before installing it, and you're best off removing all third-party plugins because if iPhoto doesn't like one of them, it just refuses to do anything at all when you choose File/Export.
To remove plugins:
- Go to Applications
- Right-click iPhoto
- Choose "Show Package Contents"
- Open Contents/Plugins
- delete FlickrExport.iPhotoEx and any other third-party plugins
