When we create image  gallery it is better to show image loader rather than showing the blank page I  have created jquery image loader.
This is the loader gif img.

<script src=”http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js”>
</script>
<script>
$(document).ready(function(){
$(‘img’).hide();
$(‘img’).each( function(){
$(“<div></div>”,{
class:’loader’
}).insertBefore($(this));
$(this).load(function(){
$(this).fadeIn();
$(this).prev().remove();
});
});
});
</script>
