<?php
$p=$_GET['p']; //取参数
$pics=file($p); //远程抓取图片
//以二进制流输到浏览器，
//注意：在Ie下直接就解析成图片，但是在谷歌浏览器被解析成代码
for($i=0;$i< count($pics);$i++)
{
echo $pics[$i];
}
?>
高级引申:
但是有些地方引用的图片不能带有参数.那么下面就开始使其不带参数的代码.
<?php
error_reporting(0); //防错,这句可以不要.
$imgurl= 'http://' . substr($_SERVER["REQUEST_URI"],1); //参数不带"http://"
//这里不补去.后面的语句是取地址栏地址
pics=file($imgurl);
for($i=0;$i< count($pics);$i++)
{
echo $pics[$i];
}
?>
然后要使用URL重定向,不然就无法输出
增加或者另外写一个重定向的文件.htaccess
RewriteRule (?{1,})\.jpg$ img.php?p=$1
RewriteRule (?{1,})\.png$ img.php?p=$1
RewriteRule (?{1,})\.gif$ img.php?p=$1
最后就可以这样使用图片
这看起来就像你自己网站上的图片一样.
如果有心的话,还可以把 www.baidu.com/ 修改下,然后在代码替换下.
这样更加难以分辨..
下面是Asp的代码
