/**
 * This observer is fired after a product is prepared saving an is used to store file uploads of custom options.



* @param $observer
 */
public function catalogProductPrepareSave($observer)
{
    if(!isset($_FILES['product']) || !isset($_FILES['product']['name']) || !isset($_FILES['product']['name']['options']))
    {
        // No files are uploaded, return ...
        return;
    }
$io = new Varien_Io_File();
$dir = Mage::getBaseDir('media') . DS . 'options';
$io->open(array('path' => $dir));

/** @var Mage_Catalog_Model_Product $product */
$product = $observer->getProduct();

// Iterate through all file uploads:
foreach($_FILES['product']['name']['options'] as $optionId => $values)
{
    // Check for files:
    foreach($values['values'] as $valueId => $arr)
    {
        // Check for error code '0' (which is a successful file upload)
        if($_FILES['product']['error']['options'][$optionId]['values'][$valueId]['image'] == 0)
        {
            // Successful file upload:
            $newFileName = $arr['image'];
            $tmpFileName = $_FILES['product']['tmp_name']['options'][$optionId]['values'][$valueId]['image'];

            // Move uploaded file:
            $io->mv($tmpFileName, $dir . DS . $newFileName);

            // Store product option value of this product:
            $option = $product->getOptionById($optionId);
            $value = $option->getValueById($valueId);
            $value->setImage($newFileName);
            $value->save();
        }
    }
}

$io->close();

}
