不用插件，怎样为博客建立Gravatars
Gravatar是啥？
一个avatar是与用户交流的小图片，在很多论坛上都有，在博客上也越来越流行。 Gravatar是一个服务商，口号是“Globally Recognized Avatars“。你可以去注册一个玩玩，之后几乎不会再去访问它的网站。
注册了之后，每当你填入你的email地址，你的头像就会出现啦，当然这需要博主加上几行简单的代码。
What are the Benefits?
Draw attention to yourself. Most people comment on a website hoping for a little bit of traffic, so it makes sense that using any means within your arm’s reach is beneficial to you. A minute long process of signing up for a service and you get that attention.
People have been known to include scantily clad women, which certainly warrant a few clicks from weary lurkers in the depths of your archives. In short, a Gravatar can do a few things for you:
- Personalize. Add a picture of yourself and people will see the face behind the name and the words you write.
- Capture attention. As mentioned above, if you want clicks over a response or any shred of respect, go for shock or surprise value.
- Get recognized. Comment a lot? Authors and readers like will recognize the avatar of a commenter who consistently posts insightful musings.
In the end, you spend two minutes or so signing up and uploading a picture, and you will see the results soon after.
我们捡重点的说：
HOW TO
打开comments.php然后看下面的步骤
1 为了需要生成头像，你需要发送点儿东东
<?
$email = $comment->comment_author_email;
$default = “”; // link to your default avatar
$size = 40; // size in pixels squared
$grav_url = “http://www.gravatar.com/avatar.php?gravatar_id=
” . md5($email) . “&default=” . urlencode($default) . “&size=” . $size;
?>
There isn’t much in there to understand. Set the $email variable to whatever works with your system. The one in place works with WordPress. After that, upload an image you want to serve when the user doesn’t have a Gravatar, input a size and you’re good to go.
2 在出现头像的地方加入
<img src=”<?=$grav_url ?>” height=”<?=$size ?>” width=”<?=$size ?>” alt=”User Gravatar” />
这样就搞定鸟～
最简单的办法就是升级到2.5。哈哈
