немного доработал и получилось это:
в контроллере после:
$data['products'][] = array(
'product_id' => $result['product_id'],
'thumb' => $image,
'name' => $result['name'],
'upc' => $result['upc'],
'ean' => $result['ean'],
'jan' => $result['jan'],
'model' => $result['model'],
'description' => utf8_substr(trim(strip_tags(html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8'))), 0, $this->config->get('theme_' . $this->config->get('config_theme') . '_product_description_length')) . '..',
'price' => $price,
'special' => $special,
'tax' => $tax,
'rating' => $rating,
'href' => $this->url->link('product/product', 'product_id=' . $result['product_id'])
);
вставить:
$data['images'] = array();
$results = $this->model_catalog_product->getProductImages($result['product_id']);
foreach ($results as $result) {
$data['images'][] = array(
'thumb' => $this->model_tool_image->resize($result['image'], $setting['width'], $setting['height'])
);
}
в шаблоне в любое место:
{% for image in images %}
<img src="{{ image.thumb }}" />
{% endfor %}
