Answer 1

In my problem i have set the images for the enabled grouped product. I have set the last image as the base,small and thumbnail image.

$collection = Mage::getModel('catalog/product')
                  ->getCollection()
                  ->addAttributeToFilter("type_id",array("eq","grouped"))
                  ->addAttributeToFilter("status",array("eq","1"));
foreach($collection as $tmpProduct) {
  $sku = $tmpProduct->getSku();
  $product = Mage::getModel('catalog/product')
                 ->loadByAttribute("sku",$sku);
  $_images = Mage::getModel('catalog/product')
                 ->load($product->getId())
                 ->getMediaGalleryImages();
  $checkImage =  Mage::getBaseDir('media').DS.'catalog'.DS.'product'.DS.$product->getImage();

  if( $product->getImage()!=''  && is_file($checkImage)) {
    continue; // do nothing
  } else {
    if($_images) {
      $baseImage = '';
      foreach($_images as $_image) {
        $baseImage = $_image->getFile();
      }
      $groupedImagePath = Mage::getBaseDir('media').DS.'catalog'.DS.'product'.DS.$baseImage;
      $product->setMediaGallery(
                  array('images'=>array (),
                        'values'=>array ()));
      $product->addImageToMediaGallery(
                  $groupedImagePath,
                  array('image', 'thumbnail', 'small_image'),
                  false,
                  false);   
      Mage::getModel('catalog/product_attribute_media_api')
          ->remove($product->getId(),$baseImage);
      $product->save();  
      echo "
$sku has selected image 
";
} } }
