Plugin for mouseover zoom for image?

Hi all,

I’ve got a client that has seen something on websites on the Internet that he would like to have:

At various online stores, he has seen something where, when user “mouseovers” a picture an item that is for sale at an online store, it sort of brings up a little “zoom” and zooms into the item, as user drags mouse around the image. He states he likes this better than what a lot of other online stores do–where you have to click the item, and a little window pops up with a larger version of the image.

Anyone know of a plugin that allows you to do this, in WordPress ?

Thanks for any insight anyone can give me on this.
