Images missing alt text
What this means
One or more images have no alt attribute or an empty one. Severity rises once more than five images on the page are affected.
How to fix it
Describe what each meaningful image shows; genuinely decorative images should carry an explicit empty alt so assistive technology skips them.
Fix effort
This check needs review: the change can be drafted for you, but a person has to approve the wording or choose the target before it ships.
