HTML

<!-- Incarnation #2: Without the CSS, this shows that multiple images exist on a page at a time -->

<div id="1" class="thumbnail">
    <div class="image">
        <img src="http://lorempixel.com/100/100/animals/0" data-n="1" class="loaded"/>
    </div>
    <h1>title</h1>
    <p>description</p>
</div>

<div id="2" class="thumbnail">
    <div class="image">
        <img src="http://lorempixel.com/100/100/sports/0" data-n="1" class="loaded"/>
