I keep providing links to examples of media content that can be freely used within your own work, provided it is given appropriate attribution. Here is a link to literally millions upon millions of images that people have licensed under Creative Commons for reuse on Flickr. Thanks to all those people.
I’ve previously written about obtaining images you can freely use. I just wanted to make a quick update (though I’ve got more to write about this topic in future) about the use of Google Image Search to locate images that you can freely use. So I put together a 2min 30sec screencast to quickly explain what to do.
