<?php
if ( !empty( $comment->comment_author_email ) ) {
$md5 = md5( $comment->comment_author_email );
$default = urlencode( 'http://site.gravatar.com/images/files/thumbs/249758.jpg?413932' );
echo "<img class='gra' src='http://www.gravatar.com/avatar.php?gravatar_id=$md5&size=34&default=$default' alt='......' />";
}
?>
这一段代码，该怎么改才能让我自己回复时不显示头像而是显示昵称呢？
