Q:

Jquery fading slideshow if statement

HI I need to create a if statement for my slide show, if there is only one image I don't want the slideshow to be active;
Javascript:
    <script type="text/javascript">

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 );
});

</script>

html:
<div id="slideshow">
<img src="image1.jpg"  class="active" />

JS is not really my strong suit, any help would be great! 

A:

Change your domready function to this:
$(function() {
    if ($("#slideshow img").length > 1) {
      setInterval( "slideSwitch()", 5000 );
    }
});
