Scaleable Full size images with scroll

Hi there.

I need some urgent help. I'm working on a site and need to show images which fills 100% of the stage width, and then scrolls the length (UP & DOWN) with the mouse movement.

Basically how it is used on this site: http://www.howtospendit.com/#/brands...rolex-datejust

Click SKIP INTRO, then click on watch image, then click again to MAGNIFY.

Now you see how the image fills the screen and moves up*and down on mouse movement. That’s how I need my images to move. It also needs to be scaleable to see what I mean make the browser window a bit smaller, see how the image adjusts to screen size? Also needs to work with images that are different sizes so not fixed to 1 size.

Are all this available as a plugin or will it need to be developed, if so how do i go about coding this?

Many thanks

K
