HTML

Note: if not using bootstrap and you wish to use the hover simply remove the classes on the first div "col-lg-3 col-md-4 col-sm-6 col-xs-12" and give this div a chosen size eg width: 300px

<div class="col-lg-3 col-md-4 col-sm-6 col-xs-12">
    <div class="hovereffect">
        <img class="img-responsive" src="http://placehold.it/350x250" alt="">
            <div class="overlay">
                <h2>Effect 14</h2>
				<p>
					<a href="#">LINK HERE</a>
				</p>
            </div>
    </div>
</div>
