Doesn't quite work with touch events (e.g. ontouchstart), but has the basic principles in place.

Although they have the same problem that I do at the moment... the zoom is happening from the centre of the image, not the view port (i.e. zoom in, drag the image so you can only just see one of its edges, them zoom out again).
