It's easy to copy and paste images into your work, but you should always provide acknowledgment of an image's source. Include:
Even if your faculty member doesn’t require citation for images, it’s a good idea to include the author’s name and URL (link) as a way of informally citing it.

Helpful Hint
Wikimedia Commons is a great place to search for images that are either in the public domain, or have a Creative Commons license, meaning they can be reused without permission (but always with attribution!). In most cases, Wikimedia also shares information about the creators of images, which makes them easier to cite. Above is an image of the White Cliffs of Dover, England. Below, see the information about the photo and who created it, accessible on its Wikimedia Commons page.
The Internet provides access to lots of content that doesn’t have a clearly defined author or is in the Public Domain. In the U.S., the concept of “Fair Use” is often misunderstood to mean that you can take any information or image and use it as your own as long as it is for educational purposes. Information that is in the Public Domain still needs citation.
