Write meaningful image alternatives

The problem

Decorative art should not obscure a card's purpose for nonvisual visitors.

Practical procedure

Give functional thumbnails concise alt text describing the destination; mark purely decorative imagery appropriately.

Worked scenario

For the QA Matrix card, 'Checklist dashboard with green verification marks' conveys the visual concept.

Acceptance check

Use an accessibility tree inspector to ensure the link name and image alternative are not redundant.

Apply the method

Use the related interactive tool to try the concept on an inspectable example. Record the starting assumptions and expected result before changing settings, then compare what the tool actually does. Where the result differs, keep the release marked experimental and document the discrepancy.
