jQM - How to create image button?

Question

I am trying to create a button with an image on it. No text. I used the following and it's not working. Am I missing something?

<div data-role="footer" data-position="fixed" style="height:44px">
  <img src="Assets/logo.png" style="vertical-align:middle;margin:4px 4px 4px 4px;" align="left"/>
  <img src="Assets/whatwhyhow/what_off.png" style="vertical-align:middle;margin:10px 4px 20px 4px;padding-left:20px;" align="left"/>
</div>
