jquery - trimming image to remove div

Question

i am trying through jquery to remove a div completely when there is no child element within it. The variable I am using is an image. I can't seem to select the variable as an image, i only know how to do this through text. Could someone please help me and resolve this issue, so it detects that there is a img contained within the div and displays it and when there isn't an image it doesn't display it.

I have uploaded it through jsfiddle:http://jsfiddle.net/cLkFD/

<div class="content-container"><!--content-container-->
    <h3>title</h3>
        <div class="picture"><!--picture-->
            <img src="images/buddha.jpg" width="981" height="324" alt=""/> 
        </div><!--/picture-->
        <div class="content"><!--content-->

    $.fn.equalHeights = function(minHeight, maxHeight) {
        tallest = (minHeight) ? minHeight : 0;
        this.each(function() {
            if($(this).height() > tallest) {
                tallest = $(this).height();
            }
        });
        if((maxHeight) && tallest > maxHeight) tallest = maxHeight;
        return this.each(function() {
            $(this).height(tallest).css("overflow","hidden");
        });
    }
})(jQuery);

The above fiddle should work

$('.picture').each(function(){
    var imageElem = $(this).find('img');
    if(imageElem.length == 0) {
        $(this).hide();
    }
});

You can check to see whether any image inside your div or not using length:

$(function () {
    $('.picture').each(function () {
        if ($(this).find('img').length) {
            $(this).hide();
        }
    });
});
