“As a core part of the Twitter experience, it’s important that images shared on Twitter platform are accessible to everyone, including those who are visually impaired.” Todd Kloots, Staff Engineer states in a blog post
With this update, the company is empowering everyone to ensure content shared on Twitter is accessible to the widest possible audience.
To enable this feature by using the compose image descriptions option in the Twitter app’s accessibility settings. The next time you add an image to a Tweet, each thumbnail in the composer will have an add description button.
Tap it to add a description of up to 420 characters to the image. People who are visually impaired will have access to the description via their assistive technology.
To ensure publishers and third-party clients also have the capability to add alternative text to images, the company has also extended their platform products to both the REST API and Twitter Cards.
“We’re excited to empower our customers and publishers to make images on Twitter accessible to the widest possible audience, so everyone can be included in the conversation and experience the biggest moments together.” Todd Kloots, Staff Engineer states in a blog post
