Allow client interaction with image upload.

Here is my current site http://www.chrisfawkes.net

What i would love to do is create a section where i could have one of my art prints on the page and then a visitor could upload an image of their lounge room and then move my are print image over their lounge room image and get an idea of what it will look like on their walls.

I’ll worship the first person to help me get this going.
