    $.fn.MySlider = function(interval) {
        var slides;
        var cnt;
        var amount;
        var i;
 
        function run() {
            // hiding previous image and showing next
            $(slides[i]).fadeOut(1000);
            i++;
            if (i >= amount) i = 0;
            $(slides[i]).fadeIn(1000);
 
            // updating counter
            cnt.text(i+1+' / '+amount);
 
            // loop
            setTimeout(run, interval);
        }
 
        slides = $('#image_slider').children();
        cnt = $('#counter');
        amount = slides.length;
        i=0;
 
        // updating counter
        cnt.text(i+1+' / '+amount);
 
        setTimeout(run, interval);
    };
})(jQuery);
 
// custom initialization
jQuery(window).load(function() {
