WordPress 相关日志插件：WordPress Related Posts，这个也是由水煮鱼制作的插件，其中有一项功能可以通过自定义字段显示缩略图，对于一个新博客而言，可以慢慢添加，但是对于一个已经有几百上千的日志，如果确实需要相关日志只显示图片而不需要使用标题的类型，这个时候你去自定字段一个个修改，耗时不说，累都累死了。我想到了修改，经过在源码的基础上修改后，适用一切正常，至于漂亮与否，还需要各位自己修改了，毕竟修改PHP并且要设计的好看。

修改的主要作用是在大量文章需要设置自定义字段来达到相关日志显示缩略图时，可以使用我修改过的代码，为设置您的每篇文章的第一张图片规律性的替换,比如规律性的替换.jpg 为 _s.jpg
不仅适用于flickr,一些大型网站也是比较适合的,wordpress的自带图片库也可以适用，但是具体怎么替换后缀名需要你自己手动修改下代码。
注意:
只是一些小的改动,插件源码来自于水煮鱼
插件设置不需要勾选Related Posts with Thumbnail

下载地址：相关日志只显示缩略图插件：http://www.yisougou.com/download/relatedpost-only-display-first-images.rar

哪些地方你可能需要改动：

    $content = $related_post-> post_content;

            preg_match_all('| WP相关文章插件修改成批量添加自定义图片地址_PHP |i', $related_post->post_content, $matches);

            $img_src = $matches[1][0]; //first photo
        if (eregi("flickr.com",$img_src)){
            $img_url = str_replace(".jpg", "_s.jpg", $img_src);
            }else{
            $img_url=$img_src;
            }

以上你可以设置怎么替换图片后缀,以上只抓取每篇文章的第一张图片。

和

$output .= '';

以上你可以设置图片显示格式，有漂亮的格式教我。

这样一来，就不需要每篇文章都去修改添加自定义字段的缩略图图片地址了。
