Magento – Show Custom Multi-Select Attribute Values as Images

Here's the code I used recently for creating a product. It's based on having an array of image urls ($imgArray) rather than a single image url. It adds the first image in the array as the thumb/base/small and the rest as additional images.

It was based on MagePsycho's blog post here;

http://www.blog.magepsycho.com/how-to-import-product-images-from-external-url-in-magento/

    // We set up a $count variable - the first image gets used as small, thumbnail and base
    $count = 0;

    $mediaAttribute = array (
            'thumbnail',
            'small_image',
            'image'
        );

    foreach ($imgArray as $image) :

            $imgUrl = $this->_save_image( $image );       

            if ($count == 0) :

                $newproduct->addImageToMediaGallery( $imgUrl , $mediaAttribute, false, false ); 

            else :

                $newproduct->addImageToMediaGallery( $imgUrl , null, false, false );

            endif;

            $count++;  

    endforeach; 

And the _save_image method;

protected function _save_image($img) {

    $imageFilename      = basename($img);    
    $image_type         = substr(strrchr($imageFilename,"."),1); //find the image extension
    $filename           = md5($img . strtotime('now')).'.'.$image_type; //give a new name, you can modify as per your requirement
    $filepath           = Mage::getBaseDir('media') . DS . 'import'. DS . $filename; //path for temp storage folder: ./media/import/
    $newImgUrl          = file_put_contents($filepath, file_get_contents(trim($img))); //store the image from external url to the temp storage folder

    return $filepath;

}

If you are using similar and it isn't working you might want to look at filepaths, permissions and also reindexing as potential issues that could fix your problem.

The method getAttributeText looks like this:

public function getAttributeText($attributeCode)
{
    return $this->getResource()
        ->getAttribute($attributeCode)
            ->getSource()
                ->getOptionText($this->getData($attributeCode));
}

Notice the last 2 lines.
They mean that the method calls getOptionText from the source model class.
I see that your attribute has a custom source model npm_recurrex/package_source. Make sure that model has the method getOptionText or it's parent class has it and returns what your need.

[EDIT]
Your getOptionText is wrong.
It would work if the attribute would be of type select.
But it doesn't work for multiselects.
Here is a scenario. Actually I'm using your scenario.
$_product->getData('package') returns 1,2.
And I assume your options are something like this:

$options[] => array('value' => 1, 'label'=>'Option 1');
$options[] => array('value' => 2, 'label'=>'Option 2');
$options[] => array('value' => 3, 'label'=>'Option 3');
$options[] => array('value' => 4, 'label'=>'Option 4'); 

In this case, your method receives as parameter 1,2 and you check if there is an element in $options with value = 1,2. and there isn't.
Try to make your method look like this:

public function getOptionText($value)
{
    $options = $this->getAllOptions(false);
    $optionsByValue = array();
    foreach ($options as $item) {
        $optionsByValue[$item['value']] = $item['label'];
    }

    $values = explode(',', $value);
    $returnValue = array();
    foreach ($values as $_value) {
         if (isset($optionsByValue[$_value])) {
             $returnValue[] = $optionsByValue[$_value];
         }
    }
    return implode(', ', $returnValue);
}

Untested code so look out for typos.
