The Connected Classroom: A Lesson on Reflection: MORE Copyright Confusion...
A teacher's reflections on using images from Flickr. Although she encouraged the use of Creative Commons images, the nature of the student work clearly fell under fair use.

She wrote a really thoughtful response to the Flickr users and had a great discussion with her students about copyright.

Cute idea for comics or scenarios--create scenes with lego people or other toys. These images are licensed CC-By-NC-SA. This photographer also has an album with some of the same images and talk boxes already added.
