I've completed quite a few tutorials for Blogger as my elementary teachers are utilizing it for their classroom websites. It provides a quick and convenient manner by which teachers can communicate to the community.
I don't want to steal any of Mr. Byrne's thunder as he posted very clearly How to Add a Creative Commons Image Search Tool to Your Blog. It just provides another great resource that teachers can add to their class blog/website that would be of great use to students and parents as the images are not only legal to use but provide the proper citation. I just wanted it in my collection of Blogger tools. :)
Make sure you check it out!
