php版的代码比较简单:复制代码 代码如下:
php版的代码比较简单:
复制代码 代码如下:

<?php
$p=$_get['p'];
$pics=file($p);
for($i=0;$i< count($pics);$i++)
{
echo $pics[$i];
}
?>


使用方法:将文件保存成i.php上传到根目录
将不能外链的图片地址改成http://你的域名p.php?p=图片地址

asp版,网上用的比较多的
复制代码 代码如下:

dim url, body, mycache
url = request.querystring("url")
set mycache = new cache
mycache.name = "picindex"&url
if mycache.valid then
body = mycache.value
else

mycache.add body,dateadd("d",1,now)
end if
if err.number = 0 then
response.charset = "utf-8"
response.contenttype = "application/octet-stream"
response.binarywrite body
response.flush
else
wscript.echo err.description
end if

使用方法:将文件保存成i.asp上传到根目录
将不能外链的图片地址改成http://你的域名/p.asp?url=图片地址
