Picasso. Easy way to load next image if previous not alavailable

Question

I have a large list of links to images (List<Strings>). Is there an easy way to download the first available image? I do not want to manually catch the error and run the new loading instance (or I just do not understand how to do it simply).

I just thought that Picasso has the download/attempts queue or something like that. But I did not find anything in the documentation.

What have you tried? Can you simply do something like the following? (just off the top of my head to give the idea, not cleaned up.)

List<String> urls;
if (!urls.isEmpty()) {
  picasso.load(urls.get(0)).into(target, new Callback.EmptyCallback() {
    @Override
    public void onSuccess() {
      urls.remove(0);
      if (!urls.isEmpty()) {
        picasso.load(urls.get(0)).into(target, this);
      }
    }
  });
}
