Visual content includes pictures, clip art, SmartArt graphics, shapes, groups, charts, embedded objects, ink, and videos. Alt text helps people who can’t see the screen to understand what’s important in images and other visuals.
Avoid using text in images as the sole method of conveying important information. If you must use an image with text in it, repeat that text in the document. In alt text, briefly describe the image and mention the existence of the text and its intent.
