其中db_mysql.inc.php,config.php,function.php不是真正使用到的，关键是$filename 文件名,我是通过读取数据库中的图片名称
<?php
include_once ('inc/db_mysql.inc.php');
include_once ('inc/config.php');
include_once ('class/function.php');
global $picPath;
（本文来源于图老师网站，更多请访问http://m.tulaoshi.com/php/）if (strstr($_SERVER[HTTP_USER_AGENT],"MSIE")) {
$attachment = '';
} else {
$attachment = ' atachment;';
}
$image = getInfo('newssp_gallery','id',$_GET['id']);
（本文来源于图老师网站，更多请访问http://m.tulaoshi.com/php/）$filename = $picPath.$image['filename'];
if (!file_exists($filename)) {
$filename = $picPath."notexist.gif";
}
header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache"); // HTTP/1.0
header("Content-disposition:".$attachment." filename=".$image['original']);
$size = @filesize($filename);
header("Content-Length: $size");
$fd = @fopen($filename,rb);
$contents = @fread($fd,$size);
@fclose ($fd);
echo $contents;
?
使用的时候可以把在html文件里加上
<img src="http://img.jcwcn.com/attachment/portal"
