What it does

Checks for <img> tags that do not declare an alt attribute.

Why is this bad?

The alt attribute provides a textual alternative for screen readers and is rendered when the image cannot be loaded. Without it, assistive technologies have no way to describe the image to the user. Decorative images should declare alt="" so screen readers skip them.

Example

<img src="photo.jpg">

Use instead: 

<img src="photo.jpg" alt="A photo of the team">
