George616 says:

 function ChangeOrientation(ele) {

            ele.innerHTML = ele.innerHTML == 'Portrait' ? 'Landscape' : 'Portrait';

            var img = document.getElementById('Image3');

            var height = img.height;

            var width = img.width;

            var dv = document.getElementById('parent');

            img.style.height = width + 'px';

            img.style.width = height + 'px';

            dv.style.height = width + 'px';

            dv.style.width = height + 'px';

        }

Replace above with below and change the value as per your need.

function ChangeOrientation(ele) {
    var img = document.getElementById('Image3');
    var dv = document.getElementById('parent');
    if (ele.innerHTML == 'Portrait') {
        ele.innerHTML = 'Landscape';
        img.style.height = '340px';
        dv.style.height = '340px';
        img.style.width = '600px';
        dv.style.width = '600px';
    } else {
        ele.innerHTML = 'Portrait';
        img.style.height = '450px';
        dv.style.height = '450px';
        img.style.width = '340px';
        dv.style.width = '340px';
    }
}
