Facebook分享链接未显示帖子中图像的缩略图？

通常,facebook共享会从网站上获取要发布的图像并将其显示为缩略图.

如果在我的测试页中按"在Facebook上共享此链接",则不会.

这是我的测试站点: http://alexchen.info/taiwantalk/

这是代码:

 <?php
/**
 * Template Name: Front Page
 * @package WordPress
 * @subpackage Prominent
 * @since Prominent 1.0
 */
get_header(); ?>
<div id="tagline">
    <div class="container">
    </div><!-- .container -->
</div><!-- #tagline -->
<div id="content">
    <div class="container">
        <div id="mainbar">
            <?php while ( have_posts() ) : the_post(); ?>
                <div class="content-block-2">
                    <?php the_content(); ?>
                </div>
                <a href="http://www.facebook.com/sharer.php?u=<?php the_permalink();?>&t=<?php the_title(); ?>" target="blank">Share on Facebook</a>
            <?php endwhile; ?>
            <?php /* Display navigation to next/previous pages when applicable */ ?>
            <?php if (  $wp_query->max_num_pages > 1 ) : ?>
                <?php next_posts_link( __( '&larr; Older posts', 'twentyten' ) ); ?>
                <?php previous_posts_link( __( 'Newer posts &rarr;', 'twentyten' ) ); ?>
            <?php endif; ?>
        </div><!-- #mainbar -->
    </div><!-- .container -->
</div><!-- #content-bottom -->
<?php get_footer(); ?>
 

编辑:

我添加了所有必要的元标记和链接:

 <meta charset="<?php bloginfo( 'charset' ); ?>" />
<meta name="title" content="Article headline here" />
<meta name="description" content="Article summary here" />
<title><?php
    /*
     * Print the <title> tag based on what is being viewed.
     * We filter the output of wp_title() a bit -- see
     * twentyten_filter_wp_title() in functions.php.
     */
    wp_title( '|', true, 'right' );
?></title>
<link rel="profile" href="http://gmpg.org/xfn/11" />
<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 'stylesheet_url' ); ?>" />
<link rel="pingback" href="<?php bloginfo( 'pingback_url' ); ?>" />
<link rel="image_src" href="http://alexchen.info/taiwantalk/wp-content/uploads/2011/03/cheating.png" />
 

但这是唯一显示的内容:

您可以使用这些HTML标签和 属性:

有什么建议吗?

Usually facebook share gets an image from the site to post and shows it as thumbnails.

If you press the share this on facebook link in my test page it doesn't.

This is my test site: http://alexchen.info/taiwantalk/

This is the code:

<?php
/**
 * Template Name: Front Page
 * @package WordPress
 * @subpackage Prominent
 * @since Prominent 1.0
 */
get_header(); ?>
<div id="tagline">
    <div class="container">
    </div><!-- .container -->
</div><!-- #tagline -->
<div id="content">
    <div class="container">
        <div id="mainbar">
            <?php while ( have_posts() ) : the_post(); ?>
                <div class="content-block-2">
                    <?php the_content(); ?>
                </div>
                <a href="http://www.facebook.com/sharer.php?u=<?php the_permalink();?>&t=<?php the_title(); ?>" target="blank">Share on Facebook</a>
            <?php endwhile; ?>
            <?php /* Display navigation to next/previous pages when applicable */ ?>
            <?php if (  $wp_query->max_num_pages > 1 ) : ?>
                <?php next_posts_link( __( '&larr; Older posts', 'twentyten' ) ); ?>
                <?php previous_posts_link( __( 'Newer posts &rarr;', 'twentyten' ) ); ?>
            <?php endif; ?>
        </div><!-- #mainbar -->
    </div><!-- .container -->
</div><!-- #content-bottom -->
<?php get_footer(); ?>

EDIT:

I added all necessary meta tags and links:

<meta charset="<?php bloginfo( 'charset' ); ?>" />
<meta name="title" content="Article headline here" />
<meta name="description" content="Article summary here" />
<title><?php
    /*
     * Print the <title> tag based on what is being viewed.
     * We filter the output of wp_title() a bit -- see
     * twentyten_filter_wp_title() in functions.php.
     */
    wp_title( '|', true, 'right' );
?></title>
<link rel="profile" href="http://gmpg.org/xfn/11" />
<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 'stylesheet_url' ); ?>" />
<link rel="pingback" href="<?php bloginfo( 'pingback_url' ); ?>" />
<link rel="image_src" href="http://alexchen.info/taiwantalk/wp-content/uploads/2011/03/cheating.png" />

But this is the only thing that is shown:

You may use these HTML tags and attributes:

any suggestions?
