剛剛要上傳檔案照片時，傳完後發現照片還要分級，好好笑喔！
順便介紹一下好了，最常見的下面這幾種:
G，指的是 General，就是我們的普遍級。適合全家大小。任何觀眾都可以看的。
PG，指的是 Parental Guidance Recommended ，要有家長陪同的，也就是我們的保護級，有些不雅手勢，穿的比較清涼，或是比較不嚴重的問候別人家長，不嚴重的暴力等。
R，指的是 Restricted ，限制級的，就是有髒話，暴力，裸露，毒品使用等。
X，指的是 Explicit Sex or Extreme Violence ，性跟暴力。一般用來指 Pornography，色情片。誇張，剛剛為了確認拼字，查一下google字典裡面居然沒有這個字。不過下面有網路解釋就是了。
這邊用的Gravatar，指的是Globally Recognized Avatar 有翻做全球肖像認證，Avatar就是先前很受歡迎的阿凡達，其實就是在網路上的使用的化身的意思。
又扯了一堆，呵呵，其實每個國家的分級制都有點不太一樣。好忙的一天又要開始，先忙去囉！
A G rated gravatar is suitable for display on all websites with any audience type.
PG rated gravatars may contain rude gestures, provocatively dressed individuals, the lesser swear words, or mild violence.
R rated gravatars may contain such things as harsh profanity, intense violence, nudity, or hard drug use.
X rated gravatars may contain hardcore sexual imagery or extremely disturbing violence.
下面是從Wikipedia捉出來的台灣分級制，供大家參考囉。
