iphotoexport is an open source and command line based tool which allows you to export and synchronize your iPhoto library to a folder tree.
iphotoexport preserves both the original and modified image, your event and album organization, and applies your iPhoto titles, descriptions, keywords, and face tags to the IPTC/EXIF metadata of your images.
You can export a full copy of your library, or just build a tree of linked images that require very little additional disk space. You can re-run iphotoexport at any time to synchronize any changes made in iPhoto to your export tree quickly.
iphotoexport works well with file-system based photo management tools like Picasa or Adobe Bridge.
