[jQuery] Banner Slide Show

[zanm]

Hi group,

I am new to jQuery.  I see a lot of examples out there that show you
how to make a banner slide show.  They work great, but how do I read
images from a specific folder?

The way I have my images structured for the banner is by season.  So,
I have a group of photos in a folder labeled Winter and one for
Spring...etc.

So, how do I get the current season (using jQuery) and all images in a
given folder (using jQuery).  This would replace the HTML div tag
section below.

Here is an example script for just the slide show:

HTML:
<div id="slideshow">
    <img src="img/img1.jpg" alt="" class="active" />
    <img src="img/img2.jpg" alt="" />
    <img src="img/img3.jpg" alt="" />
</div>

STYLE:
#slideshow {
    position:relative;
    height:350px;
}

#slideshow IMG {
    position:absolute;
    top:0;
    left:0;
    z-index:8;
}

#slideshow IMG.active {
    z-index:10;
}

#slideshow IMG.last-active {
    z-index:9;
}

jQuery:
function slideSwitch() {
    var $active = $('#slideshow IMG.active');

    if ( $active.length == 0 ) $active = $('#slideshow IMG:last');

    // use this to pull the images in the order they appear in the
markup
    var $next =  $active.next().length ? $active.next()
        : $('#slideshow IMG:first');

    // uncomment the 3 lines below to pull the images in random order

    // var $sibs  = $active.siblings();
    // var rndNum = Math.floor(Math.random() * $sibs.length );
    // var $next  = $( $sibs[ rndNum ] );


    $active.addClass('last-active');

    $next.css({opacity: 0.0})
        .addClass('active')
        .animate({opacity: 1.0}, 1000, function() {
            $active.removeClass('active last-active');
        });
}

$(function() {
    setInterval( "slideSwitch()", 5000 );
});
