Web 2.0 granddaddy Dave Winer is building a service to post Flickr photos to Twitter. If you weren't one of the lucky few to get an invite, here's how to jury-rig a system to do the same thing on your own. (Winer already created Twittergrams, which I clipped earlier. With Twittergrams you can post short mp3s to Twitter. He even provides a phone interface. Extremely, extremely cool.)
