Product zoom in AlpineStars -- how to?

Hi guys,

Does anyone know of a tutorial or prototype to achieve the zoom/pan effect below?

I am looking for something that I can just drop a large image into as I have quite a few products to do in this way. File size is also a big consideration as always.

Thanks,
