Understanding Creative Commons


Creative Commons logo



Creative Commons is a non-profit organization that provides a framework to allow the reuse of creative work. Their widely recognized licenses allow creators to make their work easily reusable, with different levels of restrictions of their choice (for example, one may want to allow their work to be used for non-commercial purposes only). 

You can use images that have a Creative Commons license, but it is important to understand the types of Creative Commons license that is applied to an image, and what restrictions, if any, there may be. 

For a list of the different types of CC licenses and what you can and cannot do, see the Licenses and Examples page.

If you're considering applying a CC license to your own work, use the CC License Chooser tool.

Proper use of images

There are three situations for using images correctly in your project:

  1. Use an image that has a Creative Commons license (and adhere to the rules of the specific license applied).
  2. Use an image that is in the public domain. In general, you'll find these on the websites of credible sources (like public libraries and archives), with a clear statement indicating that the image is in the public domain.
  3. Obtain a license to use an image. This often involves paying a fee.


If an image you find has no apparent license or usage terms associated with it (for example, images on the New York Times website), you must assume it is under copyright and CANNOT BE USED WITHOUT PERMISSION of the copyright holder.

How to cite images

Regardless of whether or not credit is required, it is best practice to credit or cite an image you use. You can do this by at least adding a caption to your image and ideally, also providing a citation in a list of references at the end of your work.

See the box to the left for examples of how to cite an image in a number of citation styles.

Conveniently, several of the websites listed above provide an HTML code or copy-and-paste text that you can embed under your image to properly credit it and provide the reader with a link to the original image.  It's also best practice to add a link to the license, as shown below.

  1. Go to Getty Images and enter search terms in the search box.
  2. Filter the search to include embeddable images by clicking on the checkbox next to 'Embeddable Images' at the bottom of the left-hand menu.
  3. Click on an image and then click on the '</> Embed' button under the image.
  4. Copy and paste the Embed code into your webpage's source code. The image should appear as below, with the Getty Images information at the bottom of the image.
