Image button has no alt text

Why it matters

An <input type="image"> is a button made from a picture. Without alt text a screen reader cannot say what the button does.

How to fix it

Add an alt attribute that names the action, such as "Search" or "Send message".

<!-- Before -->
<input type="image" src="go.png">

<!-- After -->
<input type="image" src="go.png" alt="Search">
