Under United States copyright law, in most cases, the creator of an artistic work has the exclusive right to reproduce and distribute his or her work. So, when you use someone else's images in papers, presentations, or websites, it is important to make sure that your use is permissible under copyright law.
Copyright protection has its basis in the United States Constitution, which states that, “The Congress shall have Power To...promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries....” (Article I, Section 8, Clause 8).
Today, the process of copyrighting a work is automatic and does not require that the work be registered with the Copyright Office or that the © symbol be published with the work. This means that most images you find online are subject to copyright protection and should not be used in your works or shared with others unless there is an exception to this general rule that might apply to your use.
For a visual overview of the process of determining whether you can post an image on your website, go to the Should I Post this Image. Note that this image has a Creative Commons BY-NC license so it is OK to use non-commercial purposes with attibution to the creators, Pia Bijkerk and Erin Loechner.
Don't forget to document where you found the image so that you can cite the material and provide appropriate attribution!
If a work is in the public domain, it is not protected by copyright and may be used and adapted without restriction. Two broad categories of works in the public domain are (i) works published before 1923, and (ii) works of the United States government. Due to changes in copyright law over time, there are other materials that may be in the public domain due to the expiration of copyright. Cornell's Copyright Term and the Public Domain in the United States has a chart with full details. Works can also be dedicated to the public domain by their creators.
Open access works may be shared and reused, subject to any restrictions placed by the author or creator. They may be (i) freely available online, but retain copyright restrictions or (ii) freely available online and free of some or all restrictions on their use. The Creative Commons (CC) is a licensing system designed to make it easier for people to share their open access works with others.
Fair use permits limited use of copyrighted material without acquiring permission from the rights holders. It is a flexible right that allows portions of any copyrighted material to be used in new works. To determine whether a use is fair, four factors must be evaluated for each item to be used.
The analysis of these four factors is subjective, and users and copyright holders sometimes disagree on whether a particular use is fair. If you are considering fair use, check out our Fair Use page first.
If none of the options listed above applies to the work you want to use, you will need to ask for permission from the copyright holder. Unfortunately, getting permission to use copyrighted works can be a very frustrating and time-consumoing experience and it is hard to predict in advance what the results will be.
