One way is to place a description around the image; another is to code it with descriptive words in an "alt attribute" that is invisible on screen but can be read by screen readers.
If an image or other non-text element adds meaning to the page, then use the alt attribute to provide alternative text.
The alt attribute allows users to specify alternative text for the image if it cannot be displayed on the browser being used.
