What it checks
<input type="image"> without alt, aria-label or aria-labelledby.
Why it matters
The button (often "submit" or "search") is announced with no name, so screen-reader users cannot use the form.
Recommended fix
Add alt text that says what the button does.
How to verify
Check with axe or a screen reader that each image button is announced with its action.
Example fix prompt

Issue A11Y-017: Image buttons have no text alternative
Site: https://your-app.example
First confirm the issue in the code or live config. If it is not present, say so and change nothing.
Task: Add an alt attribute describing the action (for example alt="Search") to each <input type="image"> in the evidence.
Constraints: make the smallest change that fixes this, keep the current design and behaviour, never paste secret values into code or chat, and tell me which files you changed.
Done when: Check with axe or a screen reader that each image button is announced with its action.
