[SOLVED] Save image from URL to images field in repeater via API

[Tyssen]

I'm working with an XML feed which provides image URLs that I want to save to an images field in a repeater. So far I have this:

foreach($page->goodreads as $goodreads) :

  $xml_string = $cache->get($goodreads->isbn, 3600, function() use($goodreads_api, $goodreads) {
    return curl_get_contents('https://www.goodreads.com/search/index.xml?key='.$goodreads_api.'&q='.$goodreads->isbn);
  });
  $book_xml = new SimpleXMLElement($xml_string);

  foreach ($book_xml->search->results->work as $book) :

    $goodreads->of(false);
    $goodreads->images->add($book->best_book->image_url);
    $goodreads->save();
    $goodreads->of(true);

  endforeach;

endforeach;

I've tested that $book->best_book->image_url does actually return a value and have also tested the above with a hard-coded image URL but in both cases, no image is saved. What am I missing?

Figured it out in the end. Coded above would work fine, but I had other conditionals in place which were preventing parts of it from running.
