Best Practice 1.1 – Provide text alternatives for non-text contents (Baseline level)
Ensure that all buttons, pictures, icons, photos and images (except CAPTCHA and images used for decoration, formatting or invisible), must have a meaningful and concise text description so that it can be read by screen readers. Text alternatives should be kept short (e.g. around four-word length) as far as possible.

After Rectification The text description enable users reading the mobile application screen page to know what the image is about and what it is supposed to illustrate. |
