Free Public Domain Images

The use of media, such as images, can significantly enhance the reader's understanding of written text. One of the challenges in writing is the ethical use of images.  For example, any image that I used for our Informatics and Nursing textbook must be either one that I create or one that is in the public domain.  The ethical use of images holds true for student submitted work.  The reason is that everything is copyrighted automatically after the creation, whether or not there is a copyright icon. That is the reason that many of the figures and images in our textbook were created by Linda and myself.

However, there are many resources to public domain images that are free of copyright restrictions.  Wikipedia has many of the resources listed at
