- After uploading an image to a tweet, select Add description underneath the image
- Enter a description of the image in the text box. The character count is in the corner of the box; you have 1,000 characters available
- Click Save, and an ALT badge will appear in the corner of the image
- Tweet. If someone clicks on the ALT badge, the description should appear on-screen
Prior to Thursday’s update, the majority of users did not have access to alt text descriptions unless they were using screen readers. Twitter added picture captions in 2016, but they might be difficult to identify and add. The organisation did not have a dedicated accessibility team until late 2020, with employees offering their time to work on accessibility concerns.
