Alt text and images described in surrounding text thread

Hi again,

I’m wondering what alt text best practices are for images that are already described in text. I know that it is not best practice to repeat information that readers have already read in the body text. If an image is already sufficiently described in the text, however, what should be included in the alt element? Is it alt=””, like a decorative image? Do such images require an aria-describeBy element?

Hi again krollans,

Thanks for your question!

Yes, for images sufficiently described by surrounding text or figcaptions, you would code the image like a decorative image, with alt=”” and role=”presentation”. There is no aria-describedby requirement for these images.
