codice:
var GALLERY =
{
	container: '#gallery',
	url: '../chapter_06/08_ajax_image_gallery_improved/getImages',
	delay: 5000,

	load: function()
	{
		var _gallery = this;
		jQuery.ajax(
		{
			type:"get", 
                        url: this.url, 
			beforeSend: function()
			{
				jQuery(_gallery.container)
				.find('img')
				.fadeOut('slow', function()
				{	jQuery(this).remove();	});
			},
			success: function(data)
			{
				var images = data.split('|');
				jQuery.each(images, function()
				{	_gallery.display(this);	});
			},
			complete: function() {
			setTimeout(function()
			{
				_gallery.load();
			},
			_gallery.delay);
			}
		});
	},
	display: function(image_url)
	{
		jQuery('<img></img>')
		.attr('src', '../images/' + image_url)
		.hide()
		.load(function()
		{
			jQuery(this).fadeIn();
		})
		.appendTo('#gallery');
	}
}

jQuery(document).ready(function(){
  GALLERY.load();
});
Il codice sopra postato sembra funzionare con jquery 1.4.
Come potrei convertire il tutto per jquery 1.5 o 1.6..
