Today, I decided to license a bunch of my New Zealand pictures to creative commons. The reason I had postponed it for so long was because the flickr UI needs to traverse two pages to actually mark a photo with a license. Since this sucked totally, I sat down and wrote a small greasemonkey hack to set the licenses as well from the batch edit page. This meant that I just had a single click to edit a pic which was pretty OK. You can get the script from here. Greasemonkey is indeed a powerful tool in the hands of people who really want something done - except that they don't have access to deployed web code.
These are the photos I have licensed as creative commons. It might be a good idea to turn on javascript (or hit the original) for full effect.
Your picture of the world often changes just before you get it into focus.
