Good news! The Art Institute of Chicago has launched both a new website and a new Open Access policy for more than 44,000 of the images you’ll find on it. Like the Metropolitan Museum of Art and the Walters Art Museum before it, the AIC has released its images into the public domain under a Creative Commons Zero (CC0) license, which is the least restrictive kind you can use. This means that you are free to download and reuse these images for any purpose–even a commercial one–without having to pay a fee or seek any additional permission. As always, this only applies to the museum’s images of artworks which are themselves in the public domain, so most modern and contemporary art (including Picasso’s Old Guitarist and Edward Hopper’s Nighthawks) is excluded from the policy.
