I am having trouble implementing a tooltip using CSS for an <img> element.
While I have successfully added a tooltip to <a href> </a> tags, applying the same functionality to an <img> tag has proven difficult.

How can I make the tooltip display when hovering over the <img> element?
/* Custom styles for adding tooltips */
img,
[data-tooltip],
.tooltip {
position: relative;
cursor: pointer;
}
/* Base styles for the whole tooltip */
img:before,
img:after,
[data-tooltip]:before,
[data-tooltip]:after,
.tooltip:before,
.tooltip:after {
position: absolute;
visibility: hidden;
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0);
opacity: 0;
/* Vendor-prefixed transition property */
-webkit-transition:
opacity 0.2s ease-in-out,
visibility 0.2s ease-in-out,
-webkit-transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
-moz-transition:
opacity 0.2s ease-in-out,
visibility 0.2s ease-in-out,
-moz-transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
transition:
opacity 0.2s ease-in-out,
visibility 0.2s ease-in-out,
transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
-webkit-transform: translate3d(0, 0, 0);
-moz-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);
pointer-events: none;
}
/* Make the entire tooltip visible on hover and focus */
img:hover:before,
img:hover:after,
img:focus:before,
img:focus:after,
[data-tooltip]:hover:before,
[data-tooltip]:hover:after,
[data-tooltip]:focus:before,
[data-tooltip]:focus:after,

opacity: 1;
}

<a href="#" data-tooltip="This is a test">Test1</a>
<a href="#" class="tooltip" data-tooltip="THIS IS A TEST">Test2</a>
<img src="http://ctrlable.com/site/wp-content/uploads/2015/03/ctrlable_logo_white_cyan.png" class="tooltip" data-tooltip="THIS IS A TEST">
What am I missing in my code for the tooltip on the <img> element to function properly?
