-
If possible only include images that advance meaning.
-
If decorative text is used, it should be described as decorative image in the alt-text field.
-
Alt-text should be succinct and descriptive.
-
Screen readers announce images, so avoid using redundant language such as "graphic of" or "image of".
-
Complex images, such as graphs and charts need alt-text or descriptive captioning. Guidance for complex images is available on the Webaim.org website.
