Colorbox callback on gallery/ grouped photos/ slideshow?

Question

Hi, I have a gallery setup to find the next span, this works, but the gallery navigation(next/previous/imageclick) is not passing the callback.

$("a[ rel='gallery']").colorbox({
    onLoad:function(){
        $(this).next('span').show().prependTo($('#cboxContent'));   
        $('span').addClass("current");
        }
});

I tried something like this:

$('#cboxNext, #cboxPrevious, #cboxPhoto, #cboxClose').click(function (e) {
    $('span').removeClass('current');       
    return false;
});

Seems to be working also, but how would I pass it so it will remove the showing span and show only the next span?

$('span').remove(); with class current?
