Ok, I have tried all 3 examples and even tried a few variations that you
have given me and so far nothing is getting displayed, is there a way to
check for errors?  here is the code I am working with:

// second selection for main image on main page
$dir_name = "/path/to/images/directory/";
$dir = opendir($dir_name);
$file_lost .= "<p><FORM METHOD=\"post\" ACTION=\"done.php3\"
NAME=\"images\">
<SELECT NAME=\"images\">";
 while ($file_names = readdir($dir)) {
  if ($file_names != "." && $file_names !=".." &&
eregi("^/*_[0-9]{4}\.jpg$", $file_name)) {
  $file_lost .= "<OPTION VALUE=\"$file_names\"
NAME=\"$file_names\">$file_names</OPTION>";
  }
 }
 $file_lost .= "</SELECT><br><br><INPUT TYPE=\"submit\" NAME=\"submit\"
VALUE=\"select\"></FORM></p>";
 closedir($dir);
