  a regular sort will do the trick, but it is case sensitive. So if you have filenames that aren't all lower case, the sort won't be exact...

  So you would need a sort function to surpass the case problem like:

  function alphebetize ($a, $b) {
  $sort_two[0] = strtoupper($a);
  $sort_two[1] = strtoupper($b);
  sort($sort_two);
  return (strcmp (strtoupper ($sort_two[1]), strtoupper($b) ) ) ? 1 : -1;
  }

  Then you set up your file array (pngs and jpgs only without the . and ..)

  while ($file = readdir($handle))
  if ($file != "." &&
  $file != ".." &&
  ( ereg(".jpg",$file) ||
  ereg(".png",$file) ) ) {

  $file_list[] = $file;
  }
  }

  and then use your alphabetize function:

  usort($file_list, "alphebetize");

  I have an example at http://photos.enobrev.com/

  Let me know if you need the code.
