$url='./';
//图片地址,用相对路径
$files=array();
if ($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]");
