count child elements of a parent element using jquery

hi I am using this code below to count the img elements inside the div gallery 

<script type="text/javascript">
 var numimg=$("#gallery > img").size();

 document.write(numimg);
</script>

<div class="slide" id="gallery">
             <img src="images/6.jpg"/>
             <img src="images/7.jpg"/>
            <img src="images/8.jpg"/>
                        <img src="images/9.jpg"/>
                        <img src="images/10.jpg"/>
            <img src="images/11.jpg"/>
    </div>

Pretty sure you need to do demo here

$(function(){
var c = $('#gallery  img').length;
$('#imgcount').html(c);
});

Replace

$("#gallery > img").size();

with

$("#gallery > img").length;

and wrap code inside document.ready as below.

$(function(){
    $("#gallery > img").length;
});

There are multiple problems, your code needs to be inside the dom ready handler, after dom ready don't use document.write, and use the length property to get the number of child elements

jQuery(function(){
    var numimg=$("#gallery > img").length;
    $('body').append(numimg)
})

If you want to add the count to specific location of the page, then you can add a place holder element and then add the content to it

<span id="imgcount"></span>
<div class="slide" id="gallery">
    <img src="images/6.jpg"/>
    <img src="images/7.jpg"/>
    <img src="images/8.jpg"/>
    <img src="images/9.jpg"/>
    <img src="images/10.jpg"/>
    <img src="images/11.jpg"/>
</div>

then

jQuery(function(){
    var numimg=$("#gallery > img").length;
    $('#imgcount').html(numimg)
})

Demo: Fiddle
