Wikimedia Commons is a great platform where you can have access to over 20 million freely usable media files. Students can use these resources to search for images, sounds and clips to re-use in their multimedia projects in class. While most of the content in Wikimedia Commons is in public domain or under open content licenses, students should nonetheless verify the copyright status of each image just as they would do when obtaining images from other sources.
