Correctly iterating through array and open pages with CasperJS

I'm working on a little project with CasperJS. The main idea is to get a links to pictures with title and description from subpages of some website. I already tried many different ways to achieve what I want, but I'm stuck with some piece of code and I don't want to continue with uncorrectly way of coding for "probably very easy thing". I just started using CasperJS, so I think that the solution to my problem must be easy.

This is current sequence of events in my code:

casper.start(url);
casper.thenEvaluate(openPicturesSubpage);
casper.then(getPicturesInfo);
casper.then(getPictureFullRes);
casper.run();

First two commands are working as expected, so I will skip to the structure of third function. The code of function (I'm using jQuery, because I need to get some specific stuff in other function) getPicturesInfo (variable pictures is global):

getPicturesInfo = function() {
  pictures = this.evaluate(function() {
    var array = [];
    $('.picture-box a').each(function() {
      arr.push({
        'name': $(this).text(),
        'subpage': $(this).attr('href')
      });
    });
    return array;
  });
}

Basically I have everything I need to continue "browsing" for actual full resolution links of pictures. So the next step is to append new data to already created array. This is also the main problem I want to solve. How to correctly iterate through array of previously saved data? So there's the code of the last function getPictureFullRes:

getPictureFullRes = function() {
  for (var i = 0; i < pictures.length; i++) {
    this.thenOpen(pictures[i]['subpage'], getFullResLink);
  }
}

The problem there is that I can't pass counter variable i to my nect function getFullResLink. I also tried to add another argument to thisOpen method and argument to getFullResLink function, but it doesn't work, because method don't have that functionallity.

How could I access appropriate index of array inside getFullResLink? Thanks for any help!
