FAQ
Can I use empty alt text?
Yes, but only for decorative images. Informative images need meaningful text that matches the image purpose in context.
Can automation judge whether alt text is meaningful?
No. Automation can find missing attributes, but a person must confirm whether the text is accurate and useful.
