In a bid to make images more accessible to everyone, – including the visually impaired – Twitter has announced its users can now add descriptions to images in Tweets.
With descriptions, known as alternative text (alt text), people using Twitter’s iOS and Android apps are empowered to ensure content shared on Twitter is accessible to the widest possible audience.
Users can enable this feature by using the compose image descriptions option in the Twitter app’s accessibility settings. The next time a user adds an image to a Tweet, each thumbnail in the composer will have an add description button.
To add a description to the image, all the user is required to do is tap the button. People who are visually impaired will have access to the description via their assistive technology (e.g., screen readers and braille displays).
Descriptions can be up to 420 characters!
“Photos have been at the center of some of the biggest moments on Twitter. As a core part of the Twitter experience, it’s important that images shared on our platform are accessible to everyone, including those who are visually impaired,” Twitter stated in a blogpost.
To ensure publishers and third-party clients also have the capability to add alt text to images, Twitter has extended its platform products to both the REST API and Twitter Cards.
Twitter added, “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.”
