Rob Miles has written an interesting Flickr Photo plug-in for Windows Live Writer.  It's still pretty early, but he's released the download and will release source soon.  This is fantastic news IMO.

Update: Tim Heuer mentioned there is another plug-in is also available for Flickr  at www.flickr4writer.com.  Very nice.

Now will someone write a "What I'm Listening To" and a "Current Mood: " plug-in to append these to the bottom of my posts?  I always liked that about LiveJournal.
