一个wordpress用了ngg相册，大概有2万张图片，速度慢的不行，关掉了ngg，速度就正常了，于是写了段代码，兼容ngg gallery的singlepic写法，能正常显示图片，网站速度恢复正常。
莫名其妙的插件，怎么能把速度搞这么慢。这段代码可以用作NextGEN Gallery停用后的一个解决方案

<?php
/*
Plugin Name: fcuk ngg gallery
Plugin URI: http://www.juyimeng.com

*/
 
function ngg_pic_replacer($content) {
        $search = "@\\
no images were found
@i";
        $content= preg_replace_callback( $search, replace_picture , $content,-1);
        return $content;
}
function replace_picture($matches) {
        global $post, $wpdb;
        $picture_id = $matches['id'];
        $sql="SELECT * FROM {$wpdb->prefix}ngg_pictures p left join {$wpdb->prefix}ngg_gallery g on p.galleryid=g.gid  WHERE p.pid = ".
		intval( $picture_id ) . " ORDER BY sortorder, pid ASC";
        $ngg_image = $wpdb->get_row( $sql );
        $append="";
        if ($matches['width']) $append.=" width=".$matches['width'];
        if ($matches['height']) $append.=" height=".$matches['height'];
        if ($matches['float']) $append.=" align=".$matches['float'];
        return "<a href=\"/".$ngg_image->path."/".$ngg_image->filename."\"><img class=\"alignnone size-full\" alt=\"image\" ".$append.
		" src=\"/".$ngg_image->path."/thumbs/thumbs_".$ngg_image->filename."\"/></a>";
}
add_filter('the_content', 'ngg_pic_replacer');
add_filter('the_excerpt', 'ngg_pic_replacer');
?>

部分代码有问题，我是否要发布到wordpress上呢？
