[Plugin: NextGEN Gallery] I found two errors in the XML-RPC

1° When creating a new gallery, she does not return the same id, error in function to create: I recommend a place depending on the option to return the ID, (this work)

Here is how I did

function create_gallery($gallerytitle, $defaultpath, $output = true, $returnID = false) {

		global $wpdb, $user_ID;

		// get the current user ID
		get_currentuserinfo();

		//cleanup pathname
		$galleryname = sanitize_file_name( $gallerytitle );
		$galleryname = apply_filters('ngg_gallery_name', $galleryname);
		$nggpath = $defaultpath . $galleryname;
		$nggRoot = WINABSPATH . $defaultpath;
		$txt = '';

		// No gallery name ?
		if ( empty($galleryname) ) {
			if ($output) nggGallery::show_error( __('No valid gallery name!', 'nggallery') );
			return false;
		}

		// check for main folder
		if ( !is_dir($nggRoot) ) {
			if ( !wp_mkdir_p( $nggRoot ) ) {
				$txt  = __('Directory', 'nggallery').' <strong>' . $defaultpath . '</strong> '.__('didn\'t exist. Please create first the main gallery folder ', 'nggallery').'!<br />';
				$txt .= __('Check this link, if you didn\'t know how to set the permission :', 'nggallery').' <a href="http://codex.wordpress.org/Changing_File_Permissions">http://codex.wordpress.org/Changing_File_Permissions</a> ';
				if ($output) nggGallery::show_error($txt);
				return false;
			}
		}

		// check for permission settings, Safe mode limitations are not taken into account.
		if ( !is_writeable( $nggRoot ) ) {
			$txt  = __('Directory', 'nggallery').' <strong>' . $defaultpath . '</strong> '.__('is not writeable !', 'nggallery').'<br />';
			$txt .= __('Check this link, if you didn\'t know how to set the permission :', 'nggallery').' <a href="http://codex.wordpress.org/Changing_File_Permissions">http://codex.wordpress.org/Changing_File_Permissions</a> ';
			if ($output) nggGallery::show_error($txt);
			return false;
		}

		// 1. Create new gallery folder
		if ( !is_dir(WINABSPATH . $nggpath) ) {
			if ( !wp_mkdir_p (WINABSPATH . $nggpath) )
				$txt  = __('Unable to create directory ', 'nggallery').$nggpath.'!<br />';
		}

		// 2. Check folder permission
		if ( !is_writeable(WINABSPATH . $nggpath ) )
			$txt .= __('Directory', 'nggallery').' <strong>'.$nggpath.'</strong> '.__('is not writeable !', 'nggallery').'<br />';

		// 3. Now create "thumbs" folder inside
		if ( !is_dir(WINABSPATH . $nggpath . '/thumbs') ) {
			if ( !wp_mkdir_p ( WINABSPATH . $nggpath . '/thumbs') )
				$txt .= __('Unable to create directory ', 'nggallery').' <strong>' . $nggpath . '/thumbs !</strong>';
		}

		if (SAFE_MODE) {
			$help  = __('The server setting Safe-Mode is on !', 'nggallery');
			$help .= '<br />'.__('If you have problems, please create directory', 'nggallery').' <strong>' . $nggpath . '</strong> ';
			$help .= __('and the thumbnails directory', 'nggallery').' <strong>' . $nggpath . '/thumbs</strong> '.__('with permission 777 manually !', 'nggallery');
			if ($output) nggGallery::show_message($help);
		}

		// show a error message
		if ( !empty($txt) ) {
			if (SAFE_MODE) {
			// for safe_mode , better delete folder, both folder must be created manually
				@rmdir(WINABSPATH . $nggpath . '/thumbs');
				@rmdir(WINABSPATH . $nggpath);
			}
			if ($output) nggGallery::show_error($txt);
			return false;
		}

		$result = $wpdb->get_var("SELECT name FROM $wpdb->nggallery WHERE name = '$galleryname' ");

		if ($result) {
			if ($output) nggGallery::show_error( _n( 'Gallery', 'Galleries', 1, 'nggallery' ) .' <strong>' . $galleryname . '</strong> '.__('already exists', 'nggallery'));
			return false;
		} else {
			$result = $wpdb->query( $wpdb->prepare("INSERT INTO $wpdb->nggallery (name, path, title, author) VALUES (%s, %s, %s, %s)", $galleryname, $nggpath, $gallerytitle , $user_ID) );
			// and give me the new id
			$gallery_id = (int) $wpdb->insert_id;
			// here you can inject a custom function
			do_action('ngg_created_new_gallery', $gallery_id);

			// return only the id if defined
			if ($return_id)
				return $gallery_id;

			if ($result) {
				$message  = __('Gallery %1$s successfully created.<br/>You can show this gallery with the tag %2$s.<br/>','nggallery');
				$message  = sprintf($message, $galleryname, '[nggallery id=' . $gallery_id . ']');
				$message .= '<a href="' . admin_url() . 'admin.php?page=nggallery-manage-gallery&mode=edit&gid=' . $gallery_id . '" >';
				$message .= __('Edit gallery','nggallery');
				$message .= '</a>';

				if ($output) nggGallery::show_message($message);
			}

			if($returnID){
				return $gallery_id;
			}
			else{
				return true;
			}
		}

2° I’m having trouble using the image upload, maybe the function is wp_upload_bits () that is the problem. You can simplify this step upload ..
