Facebook, Inc. is taking the next step in its effort to battle fake news, starting with an Instagram feature that hides photoshopped images.

Discovered by San Francisco-based photographer Toby Harriman, the latest feature will add a black “False Information” warning on images deemed to be altered. Users, however, still have the choice to view the actual image, as well as read up on why the photo was hidden in the first place.

Harriman came across a hidden image on his feed but found out it was only a photo of a man standing on rainbow-colored mountains. “Looks like Instagram x Facebook will start tagging false photos/digital art,” the photographer wrote in a Facebook post.

According to Instagram, the app determines the authenticity of an image using “a combination of feedback from our community and technology.” The photo is then passed on to third-party independent fact-checkers. If the image is deemed fake, the “False Information” warning message will be placed on the image. These “fake” photos will also be removed from Instagram’s Explore and Hashtag pages and will be automatically flagged in future posts.
