Problem with ocasional blank value

["Joey" <Joey@xxxxxxxxx>]

Hi All,

 

I have a problem that the below code which is supposed to display a random
image and on occasion it shows NO image.

I'm not sure what is happening.  This is running on linux just in case that
makes any difference.

 

<%

$image_folder = "new_random/";

$dir = $_SERVER['DOCUMENT_ROOT'] . "/" . $image_folder;

$image_array = array();

 

# The user doesn"t need to see any errors

$dir_handle = @opendir($dir);

 

while (false !== ($file = readdir($dir_handle)))

  if (!is_dir($file))

    $image_array[] = $file;

#

closedir ($dir_handle);

 

#

# The following appears to make things more random

srand((double)microtime()*1000000);

$r = rand(0,sizeof($image_array)-1);

 

#

echo "<img src=\"{$image_folder}{$image_array[$r]}\" width = \"561\" height
= \"400\" >";

%></td>

 

 

 

Thanks!
