Decorative Image Not Hidden From Screen Reader Users

1.1.1 — Non-text Content

Scenario

Setting

A university's online course catalog

What’s wrong

A purely decorative image is not marked as decorative, so screen readers stop on it and announce something useless.

Example

<img src="chart.png">

Why it matters

Blind and low-vision people using screen readers, and anyone who browses with images disabled, when icons or photos carry meaning.

How to test

Inspect the image's alt attribute: decorative images (borders, spacers, dividers) must have alt="" or role="presentation" — if a screen reader announces anything for it, it fails.

How to fix

Mark decorative images with empty alt (alt="") or role="presentation" (code that strips an element's meaning) so assistive technology skips them.

<img src="chart.png" alt="Q3 revenue chart showing 12% growth">

The alt attribute gives assistive technology the same information the image conveys visually.

Outcome

On a university's online course catalog, this barrier is gone for blind and low-vision people using screen readers — they reach the same outcome without extra effort.

Who is affected

Blind and low-vision people using screen readers, and anyone who browses with images disabled, when icons or photos carry meaning.
