Gallery display the images

Hi,

On the home page I'm trying to display 4 images from the latest gallery post. I can only work out how to display the primary image (4 times).

Home Page

        <?php 
                    $opts = array(
                        'template'=>'home',
                        'image'=>true,
                        'sort-order'=>'DESC',
            'count'=>'1'
                    );
                    perch_gallery_album_listing($opts);

home.html

<perch:before>

<div class="wrap">
    <h3><strong>Why</strong> we do it</h3>


    <h4><perch:gallery id="albumTitle" /></h4>
    <p><perch:gallery id="albumExcerpt" /></p>

    <div class="clear"><br /></div>

    <span class="button">
        <a href="/projects/album.php?s=<perch:gallery id="albumSlug" />">Find out more</a>
    </span>

</div>

    <div class="images">

</perch:before>

        <a href="/projects/<perch:gallery id="main" />" title="<perch:gallery id="imageAlt" />">
            <img src="<perch:gallery id="small" />" alt=""/> 
        </a>

        <a href="/projects/<perch:gallery id="main" />" title="<perch:gallery id="imageAlt" />">
            <img src="<perch:gallery id="small" />" alt=""/> 
        </a>

        <a href="/projects/<perch:gallery id="main" />" title="<perch:gallery id="imageAlt" />">
            <img src="<perch:gallery id="small" />" alt=""/> 
        </a>

        <a href="/projects/<perch:gallery id="main" />" title="<perch:gallery id="imageAlt" />">
            <img src="<perch:gallery id="small" />" alt=""/> 
        </a>
