display image verification issue

[php_begins]

i have a code that generates a random code and displays it as an image. But the problem the image can be displayed only if it is called before any other output. How do i run it so that it can be displayed after any output..

 

 

<?
//Security Word for the form

$codelenght = 10;
while($newcode_length < $codelenght) {
$x=1;
$y=3;
$part = rand($x,$y);
if($part==1){$a=48;$b=57;}  // Numbers
if($part==2){$a=65;$b=90;}  // UpperCase
if($part==3){$a=97;$b=122;} // LowerCase
$code_part=chr(rand($a,$b));
$newcode_length = $newcode_length + 1;
$newcode = $newcode.$code_part;
}

header('Content-Type: image/png');
$im = imagecreatetruecolor(200, 40);
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$blue = imagecolorallocate($im, 0, 0, 238);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 1, 1, 200, 40, $white);
$font = '/home/vhosts/master_files/advertising/fonts/arialbd.ttf';
imagettftext($im, 12, 0, 10, 18, $blue, $font, $newcode);
imagepng($im);
imagedestroy($im);

?>

You can't. A script can output either an image or HTML - not both.

rough idea...

 

newimage2.php

<?PHP
echo "see how it works";
?>
<img src="newimage.php" alt="">
<?PHP
echo "did it work";
?>

 

newimage.php

<?PHP
$newcode = "test";
header('Content-Type: image/png');
$im = imagecreatetruecolor(200, 40);
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$blue = imagecolorallocate($im, 0, 0, 238);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 1, 1, 200, 40, $white);
$font = 'arial.ttf';
imagettftext($im, 12, 0, 10, 18, $blue, $font, $newcode);
imagepng($im);
imagedestroy($im);
?>
