Remove animation from "Person" element

Hi,

When I move a moues over a “Person element” http://blueowlcreative.com/wp/fortuna/person-element/

On Safari browser i see a bug – person’s image becomes square for a moment as it’s zooming in. It works fine in Chrome and Firefox. Unfortunately i need to make it look good for mac users as well

Can i remove the “zoom in” animation from Person element completely? So it’s just an static image. Thanks in advance!
