More and more images are openly available for reuse, reproduction, and remixing. Many of these images can be identified by Creative Commons licenses that allow the creators or owners of an image to indicate how and in what circumstances their work is available to use. An increasing number of search tools, digital galleries, and open libraries can also help you find images that are legally available to use.
In addition to museum collections, crowd-sourced image collections are often made available for use and re-use through Creative Commons licenses.
