Sexy Image Hover Effects using CSS3

First of all thanks to giving me a great response on Ajax Style Loading Animation in CSS3 ( no Images ) .
In this post I am going to show to How to create a sexy css effect on image hover.This kinda effect you have seen before in Flash or in javascript as well.But why use Flash or js when CSS can do the same work.So lets do it …
Below I have attached the snapshot .

Now let go through the code.

HTML

<div class='img' id='img-1'>
	<div class='mask'></div>
	<img src='http://www.nikesh.me/image/01.jpg' />
</div>
<div class='img' id='img-2'>
	<div class='mask'></div>
	<img src='http://www.nikesh.me/image/07.jpg' />
</div>
<div class='img' id='img-3'>
	<div class='mask' id='mask-1'></div>
	<div class='mask' id='mask-2'></div>
	<img src='http://www.nikesh.me/image/05.jpg' />
</div>
<div class='img' id='img-4'>
	<div class='mask'></div>
	<img src='http://www.nikesh.me/image/04.jpg' />
</div>
<div class='img' id='img-5'>
	<div class='mask'></div>
	<mg src='http://www.nikesh.me/image/06.jpg' />
</div>
<div class='img' id='img-6'>
