I am creating a next button and I am trying to use a for loop to get the next image in the using and with a class i call lightbox.

$('#next').live('click',function(){
    var Picture = $('.lightbox'); // path to full sized picture, 
    var num = Picture.length
    for (i = 0; i < num; ++i) {
        $('.box img').remove();
        $('.box').append('<img align="center" id="motown" src="'+Picture[i]+'" style=" z-index:52px;" > ');
    };
});

The only problem is, instead of showing the next image it loops through all the way to the last image i the list, please help. I tried using the .next() function, it did not work. could someone please help with this.
