New Post: hopefully simple image url extraction

Hi,

love the agility pack, just discovered it recently and still learning about it.

I would need some help regarding the url (source) extraction. 

Html code:

<div class="image_bg">
    <img src="http://im0n.clkimg.com/i/pL/004/4068.jpg" itemprop="image"/>
</div>

I need to extract the URL for image, class name "image_bg" is unique (it is only used once on webpage).

Any help is greatly appreciated.

Regards
