might have coined the term "photocast" (at least I never heard it until Macworld this year), an RSS feed
containing images is certainly nothing new. Fortunately, iPhoto 6 knows this, and you can easily subscribe to non-.Mac
photocasts simply by using File > Subscribe to Photocast and entering the URL of your favorite photocast. Try our TUAW Flickr feed

I found this mentioned they had errors the first time they tried a couple feeds, but they wound up behaving on a second
try. For the record though, our Flickr feed behaved just fine for me in iPhoto 6 on my PowerBook.
