<?php include_once ("inc/db_mysql.inc.php"); include_once ("inc/config.php"); include_once ("class/function.php"); global $picPath; if (strstr($_SERVER[HTTP_USER_AGENT],"MSIE")) { $attachment = ""; } else { $attachment = " atachment;"; } $image = getInfo("newssp_gallery","id",$_GET["id"]); $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://www.zzchn.com/edu/20070912/showpic.php?id=xxx" width="50" height="50"> showpic.php及上面的那个php文件,id=xxx是数据库里的记录ID,width是缩略图的宽,height是缩略图的高,请不要同时宽高都上,例如，你要实现宽为50的缩略图，只要<img src="http://www.zzchn.com/edu/20070912/showpic.php?id=xxx" width="50">这样就可以了 源代码网供稿. |
