                $string = $match[0];
                $pos = strpos($string, '>');
                $string = substr_replace($string, ' rel="nofollow">', $pos, 1);
                $content = preg_replace($patt, $string, $content);
            }
        }

        $content = preg_replace($pattern, $replace, $content);
        return $content;
    }

以上是一个插件的代码,里面写了链接转换。
我想阻止它将原本的图片链接转换。请问应该怎么修改。不是很懂PHP。请教下各位前辈 谢谢
