Problems with Twitter’s automated image cropping came up in September. It became clear that Twitter’s image-cropping algorithm defaulted to preview white faces:

In response to this, Twitter publicly announced that work needs to be done to reduce racial bias and improve how images are displayed.

Twitter acknowledged that the way the platform is programmed to automatically crop preview images could increase harm. It acknowledged it could reduce the visibility of the range of people who use Twitter. At the beginning of October, Twitter announced that it is working to limit its reliance on machine learning-based image cropping and give Twitter users more control over the Twitter image preview.

Moving forward, Twitter says: “We hope that giving people more choices for image cropping and previewing what they’ll look like in the Tweet composer may help reduce the risk of harm.”
