Why don't show flash in my screenshots?

var webPage = require('webpage');
var flash = require('./flash');
var page = webPage.create();

page.onInitialized = function () {
    console.log('Flash successfully faked: ' + flash(page));
};

page.open('http://condor.depaul.edu/sjost/hci430/flash-examples/Examples1/Examples1.htm', function (status) {
    setTimeout(function () {
        page.render('test_flash.png');
        phantom.exit();
    }, 5000);
});

> phantomjs test_flash.js
Flash successfully faked: true
Flash successfully faked: true
