Count images or "rel" attribute

I´d like to count all images for one <div class="thumbnail"> separately.

My code:

    <div class="thumbnail">     

    <a rel="first" href="#">
        <div>
        <div></div>
        <img src="...">
        </div>
    </a>

    <div class="hidden-fb"> <!-- // CSS display: none -->                                                                                                 
        <a rel="first" href="#">
            <div>
            <div></div>
            <img src="...">
            </div>
        </a>                                               
    </div><!-- .hidden-fb -->

</div><!-- .thumbnail -->

<h2>Contains 2* images </h2>

I try this

var featureImageCount = $('div.thumbnail img').length;    
$('div.thumbnail').after('<div><h1>' + featureImageCount + ' Images</h1></div>');

But I get just for all divs "(6)"
Can I do this with jquery, that the number* of images will be automatically fill out?
Or can jquery count the items by different rel attributes?

jsFiddle

Thanks
Ogni

You need to look at each .thumbnail element individually, using .each. Then, you can use $(this) in the callback to access the actual element. From there, you can find all specific descendent <img> elements. From there, you can just use .after like you attempt to, with $(this).

$(document).ready(function () {
    $("div.thumbnail").each(function () {
        var $this = $(this),
            count = $this.children("a").children("img").length;
        $this.after("<div><h1>" + count + " Images</h1></div>");
    });
});

$('div.thumbnail').each(function () {

    var $this = $(this),
        count = $this.find('img').length;

    $this.after('<h2>', {
        text: 'Contains (' + count  + '*) image' + (count == 1 ? '' : 's')
    });

});
