adding counter to a jquery slideshow

I'm using a slideshow I've built with Javascript for my website. I would like to add a counter.

1 of 3...

slide 1 / total slide...

I can't manage to find the solution...

here is my code :

$(document).ready(function() {
    // set display:none for all members of ".pic" class except the first
    $('.image_news:gt(0)').hide();

    // stores all matches for class="pic"
    var $slides = $('.image_news');

    $slides.click(function(){
        // stores the currently-visible slide
        var $current = $(this);    
        if( $current.is($slides.last()) ) {
            $current.hide();
            $slides.first().show();
        } 
        // else, hide current slide and show the next one
        else {
            $current.hide().next().show(); 
        }
    });
});

and a fsfiddle link with example : http://jsfiddle.net/XRpeA/3/

thanks a lot for your help !

I have another thing to fix. when I have 2 or 3 slideshow on my page, it doesn't work... I'm using a repeater custom fields in my admin page, so I'm not able to know in advance how many slideshow I will need... does anyone knows how I can fix it ? here is a jsfiddle : http://jsfiddle.net/XRpeA/13/

<div id="slideframe">
    <img class="image_news" src="http://s1.lemde.fr/image/2007/07/09/534x0/933544_5_aa6d_polynesie-bora-bora_0608bcead896ce3f59fc0e2fb3cc7435.jpg" />

Another option

    // stores the currently-visible slide
    var $current = $(this);
    $current.hide();
    if( $current.is($slides.last()) ) 
    {
        $current = $slides.first();
    } 
    // else, hide current slide and show the next one
    else 
    {
        $current = $current.next();
    }
    $current.show();
    $('#counter').text('image ' + ($slides.index($current) + 1) + ' / ' + $slides.length);

Plenty of options to choose from

Just add a counter and change the html. Here is a Fiddle.

var counter = 1;
$("#counter").html("image "+counter+"/3");
$slides.click(function(){
    // stores the currently-visible slide
    var $current = $(this);    
    if( $current.is($slides.last()) ) {
        $current.hide();
        $slides.first().show();
        counter = 1;
        $("#counter").html("image "+counter+"/3");
    } 
    // else, hide current slide and show the next one
    else {
        counter++;
        $current.hide().next().show(); 
        $("#counter").html("image "+counter+"/3");
    }
});

Write this:

var count = $('.image_news').length; //length gives total length of elements
$("#total").text(count);

if ($current.is($slides.last())) {
    $("#current").text("1");//first slide
    $current.hide();
    $slides.first().show();
}
// else, hide current slide and show the next one
else {
    $("#current").text($current.next().index()+1); 
    //index() returns index, add 1 because it starts from 0
    $current.hide().next().show();
}

Fiddle here.

Give each image an id eg:1,2,3 and display the id when you are on that image.
