Twitter to Let Users Crop Their Own Image Previews

Twitter says it’s engaged on methods to give customers extra visibility and management over what photos will appear to be when a tweet is revealed.

How a picture is previewed within the tweet composer shouldn’t be the way it will present up in customers’ feeds.

Twitter intends to appropriate that:

“We are prioritizing work to lower our reliance on ML-based picture cropping by giving individuals extra visibility and management over what their photos will appear to be in a Tweet.

Going ahead, we’re dedicated to following the “what you see is what you get” rules of design, which means fairly merely: the picture you see within the Tweet composer is what it’ll appear to be within the Tweet.”

Twitter’s Response

Twitter admits it may have completed higher when designing its picture preview algorithm:

“While our analyses to date haven’t shown racial or gender bias, we recognize that the way we automatically crop photos means there is a potential for harm. We should’ve done a better job of anticipating this possibility when we were first designing and building this product.”

Twitter intends on implementing modifications to scale back the obvious bias proven within the above examples:

“We’re aware of our responsibility, and want to work towards making it easier for everyone to understand how our systems work. While no system can be completely free of bias, we’ll continue to minimize bias through deliberate and thorough analysis, and share updates as we progress in this space.”
