axe-core rule: image-alt
Images are missing text alternatives
What it is
One or more images have no alt attribute, so screen readers have nothing to announce. The image is invisible to anyone who cannot see it.
Who it blocks
Blind and low-vision visitors using screen readers, and anyone browsing with images disabled. They cannot tell what the image shows, which is critical when the image is a product photo, a chart, or a linked graphic.
How to fix it
Add an alt attribute to every img element. Describe what the image conveys, not what it looks like ("Red leather office chair, side view" rather than "image123.jpg"). If the image is purely decorative, use an empty alt attribute (alt="") so screen readers skip it.
Example fix
<!-- Before -->
<img src="/products/chair-red.jpg">
<!-- After: informative image -->
<img src="/products/chair-red.jpg" alt="Red leather office chair, side view">
<!-- After: purely decorative image -->
<img src="/decorative-divider.png" alt="">This is one of the barrier types BarrierScan checks for on every scan. Request a free accessibility scan to see whether it appears on your site, alongside the rest of the automated findings.
