Image text alternative (image)

<img> requires a descriptive alt attribute. Decorative images use alt="" and aria-hidden="true" or role="presentation":


Offscreen img missing alt attribute:

This <img> element is visually hidden by positioning but still present in the accessibility tree and has no text alternative:

Because the image has no alt attribute and is not marked as decorative with aria-hidden="true" or role="presentation", it will be treated as meaningful by screen readers but provides no information.

Note: Possible to automatically text. Can be done by checking for <img> elements without an alt attribute even if they are visually hidden using CSS positioning (e.g. large negative margins).
