Understand your report
Image alternatives give context when an image cannot be seen. This checker distinguishes a missing alt attribute from an explicitly empty attribute. That distinction matters because a decorative image may correctly use alt="", while an informative image needs wording that conveys its purpose.

Frequently asked questions
Is an empty alt attribute always a problem?
No. Decorative images often use an empty alt attribute. Review the image’s purpose before changing it.
Can this check CSS background images?
