You can now order prints from any Flickr photos. You can also do the cool stamp thing. I've been wanting to try that for a while. It sounds like more cool stuff is on the way too.

From the Flickr blog:
"At the same time, we're rolling out a pilot program allowing other businesses access to our commercial APIs - the QOOP service (previously mentioned here) for photo books and posters (and more products coming soon), backups of your Flickr photos on DVDs from Englaze, printing real U.S. stamps from Zazzle (start on one of your photos to try it), and more to be announced shortly. We're still getting started on this, but the goal is to open it up completely and give you the biggest variety of choices when it comes to doing things with your photos."
