尝试更多类似的东西：

function top()
{
    var begin = 1;
    var end = 63;
    var range = end-begin+1;
    image_num = Math.floor(Math.random()*range)+begin;

    var img = document.createElement('img');
    img.src = 'http://exttemplate.wsu.edu/extsharepoint/images/next/ext' + image_num + '.jpg'
    img.style.width = '775';
    img.style.height = '85';
    img.style.border = '0';
    document.getElementById('siteID').appendChild(img);
}

window.onload = function() {
  top();
};

并将其包含在页面底部。
