Adding photos via Gallery2 API to gallery embeded with Drupal

I'm writing script for import photos from flickr. It recieves flickr photo id via ajax and uploads photo to gallery. I have problems with adding photo to DB. I'm initializing gallery via GalleryEmbed::init($params), $gallery object created succesfuly, all required fields are filled. Then I get photo from flickr, upoad it to server (tmp file are really created). Further code below:

<code>
$lock = GalleryCoreApi::acquireWriteLock($g2id);
list ($ret, $newItem) = GalleryCoreApi::addItemToAlbum($tmpFile,
$fileName,
$title,
$summary,
$description,
$mimeType,
$g2id);

GalleryCoreApi::releaseLocks($lock);

$lock = GalleryCoreApi::acquireWriteLock($newItem->getId());

$newItem->setKeywords($tags);
$newItem->save();

print_r($newItem);

GalleryCoreApi::releaseLocks($lock);

@unlink($tmpFile);

<code>

galleryPhotoItem object is printed with all required fields - id, owner, parentId etc. There no error messages in $ret. But there any data are stored to DB May be problem is in save() method, but script doesn't terminates... Help me resolving this problem plz...
