il codice è inserito dentro l'Head

function slideSwitch() {
var $active = $('#uno IMG.active');

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

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