Applying a class to the :first-child once only when creating a list dynamically with PHP?
<p>Ok, so I'm loading a list of images by directory using PHP:</p>

<pre><code>&lt;?php
    # fetch image details
    $images = getImages("marc/img/livingrooms/");

    # display on page
    foreach($images as $img) {
        echo "&lt;li&gt;&lt;img src=\"{$img['file']}\" title=\"\" alt=\"\"&gt;&lt;/li&gt;\n";
    }
?&gt;
</code></pre>

<p>Then I'm using the Galleria JQuery plugin to style those items into a gallery:</p>

<pre><code>$(document).ready(function(){

    $('.dynolist').addClass('gallery_group'); // adds new class name to maintain degradability

    $('ul.gallery_group').galleria({
        history   : true, // activates the history object for bookmarking, back-button etc.
        clickNext : true, // helper for making the image clickable
        insert    : '#main_image', // the containing selector for our main image
        onImage   : function(image,caption,thumb) { // let's add some image effects for demonstration purposes

            // fade in the image &amp; caption
            image.css('display','none').fadeIn(1000);
            caption.css('display','none').fadeIn(1000);

            // fetch the thumbnail container
            var _li = thumb.parents('li');

            // fade out inactive thumbnail
            _li.siblings().children('img.selected').fadeTo(500,0.3);

            // fade in active thumbnail
            thumb.fadeTo('fast',1).addClass('selected');

            // add a title for the clickable image
            image.attr('title','Next image &gt;&gt;');
        },
        onThumb : function(thumb) { // thumbnail effects goes here

            // fetch the thumbnail container
            var _li = thumb.parents('li');

            // if thumbnail is active, fade all the way.
            var _fadeTo = _li.is('.active') ? '1' : '0.3';

            // fade in the thumbnail when finnished loading
            thumb.css({display:'none',opacity:_fadeTo}).fadeIn(1500);

            // hover effects
            thumb.hover(
                function() { thumb.fadeTo('fast',1); },
                function() { _li.not('.active').children('img').fadeTo('fast',0.3); } // don't fade out if the parent is active
            )
        }
    });
});
</code></pre>

<p>The issue is that I need to give the first item pulled from that list a class of "active", so the first image will be loaded into the slideshow. Everything else works right now, other than getting that first image loaded.</p>

<p>Any suggestions?</p>
