Another search engine that will go through Flickr for creative commons images. You can search by tags (not description). I like the way it specifically lists the creative commons license type the person has given the image.

A wiki-based project should not be the first time students work together. Collaborative projects work well, but only if an environment of cooperation already exists.
assignment of the project must possess two qualities. First, it must be an authentic problem or situation which must be solved collaboratively. Second, the final product must be utilized by another audience, preferably classmates to advance the learning of the entire class. In other words, the wiki cannot result in an assignment that is merely "turned in." Also teachers need to remember that the wiki is only the tool to enhance learning; the problem solving is what drives the project.
To make sure this project progresses, teachers need to instill the five components of Cooperative Learning: namely, Positive Interdependence, individual Accountability, Face to Face Interaction, Group Processing, and teaching small-group social skills. The most important of the two are Positive Interdependence and Individual Accountability.
