Flickr is a good resource to have, but as a technology teacher, I can foresee that the students would need to be reminded time and again to be mindful of copyright issues and to make sure they use the Commons area of Flickr. They simply don't always grasp the fact that just because something is on the internet, they aren't allowed to copy and paste it for whatever they want. Its so easy to do that, too.
What kind of hands-on lessons could we as teachers use to reinforce that concept? (wow, I'm blowing my mind with all this deep thinking)
