Photon is now free (via Red Ferret Journal - I likada weasel). It's an iPhoto export plugin for sending photos to your wordpress (or MovableType/Blogsom/et. al.) blog. However, I personally still don't like the Pictorialis II modification of Wordpress (good idea and work, but not quite polished). It's been difficult to get setup and definitely not recommended yet for non-hacking geeks.
However, the ability for someone, from the warm embrace of iPhoto, to post to their blog is highly appealing.
In similar news, I'll try and document some of the hacks I've made to HighEarthOrbit's Wordpress install for fellow 'Pressers.
