Probelm displaying files from directory

[Lister14]

Hello folks,

Please view the following page: http://www.roy.lu/futuraplay/

I am using this code:

$dir="./download"; // Directory where files are stored

if ($dir_list = opendir($dir))
{
while(($filename = readdir($dir_list)) !== false)
{
?>
<p><a href="<?php echo $filename; ?>"><?php echo $filename;
?></a></p>
<?php
}
closedir($dir_list);
}

1. Why does this display a . and a .. in addition to the files in the directory? - I don't want this
2. Why don't the links include the real file path? Hence the pictures won't open...

Thanks in advance for your help.

Roy
