Flickr, the photo sharing discussion tool, also has some very interesting features that allow for easy inclusion of photos in your weblog. One I just became aware of is Daily Zeitgeist. It is built in Flash, and displays recent photos from Flickr. I have mine set up to grab recent images from my account and display them in the box below.

This and other cool features of Flickr can be found the on the Flickr Blog.
