	$time = current_time('mysql');

	if ( $post = get_post($post_id) ) {

		if ( substr( $post->post_date, 0, 4 ) > 0 )

			$time = $post->post_date;

	}



	$name = $_FILES[$file_id]['name'];

	$file = wp_handle_upload($_FILES[$file_id], $overrides, $time);



	if ( isset($file['error']) )

		return new WP_Error( 'upload_error', $file['error'] );



	$name_parts = pathinfo($name);

	$name = trim( substr( $name, 0, -(1 + strlen($name_parts['extension'])) ) );



	$url = $file['url'];

	$type = $file['type'];

	$file = $file['file'];

	$title = $name;

	$content = '';



	// use image exif/iptc data for title and caption defaults if possible

		'post_title' => $title,

		'post_content' => $content,

	), $post_data );

	if ( isset( $attachment['ID'] ) )

		unset( $attachment['ID'] );



	// Save the data

	$id = wp_insert_attachment($attachment, $file, $post_id);
