I can't list all images with this code:

var imgs = page.evaluate(function(){ return document.getElementsByTagName('img'); });

for (var i = imgs.length - 1; i >= 0; i--) {

It creates an array with the correct length, but only the position 0 has an image object the others positions got null. Is this a bug or am I doing something wrong?

You can't return DOM objects to the PhantomJS context, they're bound to the page.

Depends on what you want to do... for example. you can easily return the various metadata you might care about from them:

var imgUrls = page.evaluate(function(){
  return [].slice(document.getElementsByTagName('img'), 0).map(function(img) {
    return img.href;

for (var i = imgUrls.length - 1; i >= 0; i--) {

The only type of objects you can return are essentially objects that are JSON-serializable.
