Captcha wordt geresized
ik ben bezig met een spel in PHP voor mijn profielwerkstuk maar nu kwam ik een erg merkwaardige fout tegen. ik wilde ene captcha toevoegen maar die wordt geresized, hierdoor kreeg je een langgerekte en niet echt mooie afbeelding
dit is de code van de captcha

<?php
session_start();
//imagecreatefrompng :: create a new image
//from file or URL
$img = imagecreatefrompng('black.png');
//displaying the random text on the captcha
$numero = rand(10000, 99999);
$_SESSION['check'] = ($numero);
//The function imagecolorallocate creates a
//color using RGB (red,green,blue) format.
$white = imagecolorallocate($img, 255, 255, 255);
imagestring($img, 10, 8, 5, $numero, $white);
header ("Content-type: image/png"); imagepng($img);
?>
session_start();
//imagecreatefrompng :: create a new image
//from file or URL
$img = imagecreatefrompng('black.png');
//displaying the random text on the captcha
$numero = rand(10000, 99999);
$_SESSION['check'] = ($numero);
//The function imagecolorallocate creates a
//color using RGB (red,green,blue) format.
$white = imagecolorallocate($img, 255, 255, 255);
imagestring($img, 10, 8, 5, $numero, $white);
header ("Content-type: image/png"); imagepng($img);
?>

het vreemdste is dat in alle pagina´s in de map op mijn server dit probleem zich voordoet, maar in de main map, waar mijn eigen website staat, niet voor mijn profielwerkstuk, gebruik ik dezelfde captcha maar geeft dit geen problemen
heeft iemand een idee hoe dit kan?
