In many cases, you are permitted to do so. However, as some of the images are deposited in archives with the understanding that they may not be used by others, or have various stipulations that restrict their use, you first need to ask the archive that owns the image, and purchase a copy if necessary, and agree to the conditions for using the image. As a minimum, the photographer’s name and archive should always be mentioned beneath the image. Moreover, if the copyright for the image has still not run out, you are also required to obtain permission from the copyright holder to use the image. Learn more about copyrights in
