random image display

[GDnpark]

I have an image on http://photo.danen.org (the 500x375 one) that I want to change randomly. Right now it is hardcoded to /intro/today.jpg. All images are 500x375 .jpg files, but the file names can be anything.

I would like a routine that checks the /intro directory to see how many files there are, picks a random number in that range and then selects the nth file for display.

Has anybody developed such a routine, or does anybody have a better way to approach this?

<?
$dirname = ".";

if ($dir = @opendir($dirname )) {
   while (($file = readdir($dir)) !== false) {
      if (!is_dir($file)) {
            $files[] = $file;
	     }
      }
   }  

   closedir($dir);
}

srand ((double)microtime()*1000000);
$randval = rand(0,count($files)-1);

print "RandomPic# is $files[$randval]<br>\n";
?>

Very nice and tight. I will have to try this tonight. Does this give just the file name (I think so) or a fully qualified name?

In this sample just the filename, but soon you'll see it 🙂
