Help: Calling a script that returns image from another

[mrbaseball34]

I have this script:

<?
  // scoreboard.php
  // Builds a scoreboard display
  // from text passed in $text
  // 
  // example:  scoreboard.php?text=TEXANS 34
  //
  //
  Header("Content-type: image/png");
  $font = 'dotmatrx.ttf';
  if(!isset($s)) 
    $s=15;
  $size = imagettfbbox($s, 0, $font, $text);
  $dx = abs($size[2]-$size[0]);
  $dy = abs($size[5]-$size[3]);
  $xpad=10;
  $ypad=4;
  $im = imagecreate($dx+$xpad,$dy+$ypad);
  $black  = ImageColorAllocate($im, 0,0,0);
  $yellow = ImageColorAllocate($im, 255,255,0);
  ImageRectangle($im,0,0,$dx+$xpad-1,$dy+$ypad-1,$black);
  if (strpos($text, ',') > 0 ) {
    $yfudge = ($ypad/2)-4;
  } else {
    $yfudge = ($ypad/2);
  } 
  ImageTTFText($im, $s, 0, (int)($xpad/2)+1, $dy+$yfudge, $yellow, $font, $text);
  Imagepng($im);
  ImageDestroy($im);
?>

How can I call the above from my counter script to return
the image with the counter number?

here's my counter script:

<?php
  if (file_exists("counter.txt")) 
  { 
    $fp = fopen("counter.txt", "r");  

    $counter = fgets($fp, 999);
    $tmp = $counter;
    fclose($fp);
    $fp = fopen("counter.txt", "w");
    fwrite($fp, $tmp+=1);
    fclose($fp);
  }
  $counter = number_format($counter);
  // I want to call the scoreboard.php script above
  // with the $counter variable:
?>

<?php
  if (file_exists("counter.txt")) 
  { 
    $fp = fopen("counter.txt", "r");  

    $counter = fgets($fp, 999);
    $tmp = $counter;
    fclose($fp);
    $fp = fopen("counter.txt", "w");
    fwrite($fp, $tmp+=1);
    fclose($fp);
  }
  $counter = number_format($counter);
  include("scoreboard.php");
?>
