Only the first row of images need to be loaded initially (OK, maybe the first two rows for high resolution large screen monitors).
All of the others are "below the fold" and can be loaded later.

A couple minor changes to your page...

1- add jQuery to your HEAD section
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript" ></script>

Open in new window


2- for every image that you want to delay the load:
change imgs like this:
<img alt="" src="before-after-photos_files/28.png" height="312" width="950">
<img alt="" src="before-after-photos_files/4.png" height="312" width="950">

Open in new window


to this:
<img alt="" src="" height="312" width="950" id="28">
<img alt="" src="" height="312" width="950" id="4">

Open in new window


And add the code that makes those IMG tags actually have an image in them.:
<script type="text/javascript" >
	$(document).ready(function(){
		$("#28").attr("src","before-after-photos_files/28.png");
		$("#4").attr("src","before-after-photos_files/4.png");
	})
</script>

Open in new window


The whole page won't load "faster", but if you only make the page load the first row of images "right away" the user will still see the first images right away and by the time they start scrolling, the other images should be loaded.
