CasperJS code from tutorial does not work

It's my first post here : ) I'm learning CasperJS and I have to write script who search all img's on site and check urls.

I found this tutorial from vgaltes.com

var imagesArray = [];

function getImages() {
    var scripts = document.querySelectorAll('img[src]');
    return Array.prototype.map.call(scripts, function (e) {
        return e.getAttribute('src');
    });
};

casper.start('http://fooo.fooo', function () {
    imagesArray = this.evaluate(getImages);
    var self = this;
    imagesArray.forEach(function (item) {
        if (self.resourceExists(item)) {
            self.echo(item + ' loaded');
        } else {
            var message = item + ' not loaded';
            self.echo(message, 'ERROR');
        }
    });
});

but when I run this code on CasperJS (with valid url) do not work. Nothing happens. Casper Version is 1.1

I'm the owner of vgaltes.com. As Pbk1303 said, you have to call to run function. If you read the tutorial, is the last source code posted.

casper.run(function(){
    this.echo('finished');
    this.test.done(1);
    this.test.renderResults(true);
});

Looks like you did not run the function, try adding the below code in the end

casper.run(function() {this.test.renderResults(true);});
