= 使い方

1. Windows の「スタートアップ」フォルダに fotolife.wsf を入れます
2. C:\Users\ユーザー名\Pictures\screenshot と C:\Users\ユーザー名\Pictures\screenshot\old というフォルダを作ります
3. 画像を C:\Users\ユーザー名\Pictures\screenshot に保存します
4. はてなフォトライフへのアップロードが始まります
5. 保存した画像は C:\Users\ユーザー名\Pictures\screenshot\old に移されます
6. はてなフォトライフのページがブラウザで開きます

最初に実行したときにユーザー名とパスワードを聞かれ、入力すると IE のクッキーを使ってログインします。クッキーを削除するとまたログインを求められます。

もし何度もログインするのが嫌になったら、スクリプト中の user: null, とか password: null, を書き換えてください。
