Type 3: Functional images

Functional example 1:

<button>
  <img src="functional.png" alt="Dismiss">
</button>

Functional example 2:

Wayne Enterprises home 
<a href="#">
  <img src="#" alt="Wayne Enterprises home">
</a>

This does not need to be a functional image as there is text available that describes the function. So, it be be a decorative image instead:

<button>
  <img src="functional.png" alt="">
  Dismiss
</button>

Type 4: Complex images
