Following on from the previous enlarger demo this one makes use of the general sibling selector with :hover (now that it can be made to work in Safari and Chrome) to have the large image occupy the same frame as the small image and have smooth scrolling in Safari, Chrome, Opera and Firerfox v4 beta.

IE7, IE8, IE9 and Firefox v3x will have a jumpy enlarging image but at least the general sibling selector works in all these IE browsers.
