Clear File Upload on click
<p>I have the following <strong><a href="https://jsfiddle.net/8t629359/" rel="nofollow noreferrer">jsFiddle Demo</a></strong> that allows a user to upload an image &amp; it'll display.</p>

<p>However, when the user wants to click the 'x' to remove the image, it doesn't work?</p>

<p>Can someone explain how I achieve this?</p>
