jQuery gzoom plugin

$zoom = $("#zoom01").gzoom({sW: 300,
                    sH: 225,
                    lW: 1400,
                    lH: 1050,
                    lighbox : false
                    });

You can set the zoom programmatically with:
$zoom.setZoom(50);

$(".zoom_no_lbox").gzoom({sW: 300,
                          sH: 225,
                          lW: 1024,
                          lH: 768,
                          lightbox: true
                         });

$("#zoom04").gzoom({sW: 300,
                    sH: 225,
                    lW: 1024,
                    lH: 768,
                    lightbox: true,
                    zoomIcon: 'images/gtk-zoom-in.png'
                    });
