Images, videos and other content that you did not create may enhance your presentations. Yet, it is important to make sure that you are not violating anyone's copyright. One strategy is to find public domain content to use.
Copyright.gov defines public domain as a work:
". . .no longer under copyright protection or [one that] failed to meet the requirements for copyright protection. Works in the public domain may be used freely without the permission of the former copyright owner."
Such works can be used without first seeking permission. This makes them ideal for many projects, particularly those extending beyond educational use.
Note: Even if a work is in the public domain, it is advisable to provide attribution. At a minimum, record the author for your records. This will allow you, and others, to find the original later if necessary.
There may not always be something in the public domain that fits your needs. Creative Commons-licensed content can be a good alternative. When using CC-content, ensure that you correctly attribute it to the creator. There may be additional terms of the license the content is offered under, so double-check. You can find more information about this on the Creative Commons FAQ.
Note: A Creative Commons license, does not provide blanket permission to use the content without restraint. Remember, you must provide proper attribution and ensure your use does not violate the license.
