Photon

Photon is an iPhoto plugin which allows you to export directly from iPhoto to a MovableType or TypePad blog. Developed by Daikini, Photon was abandoned and (fortunately) released as open-source. Since the last version released was PPC only, I adapted and recompiled Photon as an Universal Binary.
Photon is well known mainly due to the photoblog of Douglas Bowman.
If you are a MovableType user, you can create a similar photoblog using the templates provided by Stopdesign.

      
Update: I have received an e-mail informing me that Photon will not work with iPhoto08. Unfortuntely, I don't have a copy of iPhoto08 to test and release a compatible version of Photon. When I will upgrade my copy of iPhoto, I will post more details.
New: I have developed an export plugin for Aperture which basically does the same thing as Photon. See the page here.
