php版的代碼比較簡單：
復制代碼 代碼如下:
<?php
$p=$_GET['p'];
$pics=file($p);
for($i=0;$i< count($pics);$i++)
{
echo $pics[$i];
}
?>
使用方法：將文件保存成i.php上傳到根目錄
將不能外鏈的圖片地址改成http://你的域名p.php?p=圖片地址
asp版，網上用的比較多的
復制代碼 代碼如下:
<%
Dim url, body, myCache
url = Request.QueryString("url")
Set myCache = new cache
myCache.name = "picindex"&url
If myCache.valid Then
body = myCache.value
Else
body = GetWebData(url)
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
