发一些随机图片代码，PHP的\r
- <?php
- $url='../images'; //图片地址，只可以用./you/images这样的路径\r
- $files=array();
- if ($handle=opendir("$url")) {
- while(false !== ($file = readdir($handle))) {
- if ($file != "." && $file != "..") {
- if(substr($file,-3)=='gif' || substr($file,-3)=='jpg') $files[count($files)] = $file;
- }
- }
- }
- closedir($handle);
- $random=rand(0,count($files)-1);
- if(substr($files[$random],-3)=='gif') header("Content-type: image/gif");
- elseif(substr($files[$random],-3)=='jpg') header("Content-type: image/jpeg");
- readfile("$url/$files[$random]");
- ?>
