            <h1>RequireJS image plugin</h1>
            <p>Note that <code>waitSeconds</code> should be large enough to load all the images, otherwise module may timeout.</p>
            <p>Use this plugin only on specific cases and make sure you set a large <a href="http://requirejs.org/docs/api.html#config">waitSeconds</a> (default is 7 seconds).</p>
            <h2>Notes:</h2>
            <ul>
                <li>Image paths are relative to the HTML file by default.</li>
                <li>Support absolute paths as well.</li>
                <li>Appending <code>!bust</code> to the file name will avoid caching the image.</li>
                <li>Appending <code>!rel</code> to the file name will load image realtive to baseUrl or module path.</li>
                <li>It will always return the same image object unless you use the <code>!bust</code> flag, so you may need to clone the image element before inserting it multiple times into the same document.</li>
            </ul>
