Hi! I am a newbie in here. I try to create a simple image using php gd (in a file called index.html in the public_html folder), but there is no image show up. I have a header in html code and change it afterwards. Here is the code:

<html>
<body>
<?php

$im=imagecreatetruecolor(120, 20) or die('Cannot Initialize new GD image stream');

$text_color=imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color);

header("Content-type: image/png");

imagepng($im);
imagedestroy($im);
?>
</body>
</html>

And here is the output:
Warning: Cannot modify header information - headers already sent by (output started at /home/kimo/public_html/index.php:3) in /home/kimo/public_html/index.php on line 17
‰PNG IHDRxÉ0n¤æIDATX…í”Ià EiÕ5ÛŽóåpl{‚."YVüm‚:Hÿ-Á38.…B!äÜìQ¯ ”ò|mÐ`—j…^›§|Ê3Œrˆè:‡œ‡ ç+šGr:”Îù_«hZÑõ*&¸_´ïµé·Ù÷²jil{6￾Þè5ãÇóà²ÒO%Ž<_Vä• «œiFèºÍä¯ÕK¾åÄE?ì‘2h￾s:¡`ÜçGaFÙÓ￾9˧^=[Ù/;Ãm»Ãk 8mW&Ç+”ij%(s(ˆõ~+›E¬Ð„B!äßy￾¤Í"¥™íIEND®B`‚

Could anyone let me know what I did wrong?

1. Next time use "Go Advanced" and put your code either in PHP or CODE tags

2. Post all the code. It is complaining about line 17 and you don't have that many lines.

Hi, Nothing should be sent before header header() even a white space is not allowed and use exit() after you sent header to user, so script will terminate.

Ask yourself: why are you outputting HTML elements in an image? Remove the <html> and <body> tags. That particular error has been covered many times before on these very forums.

For the sake of closing this issue, this is what Misson is suggesting:
PHP: 
<?php
header("Content-type: image/png");
$im=imagecreatetruecolor(120, 20) or die('Cannot Initialize new GD image stream');
$text_color=imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);
imagepng($im);
imagedestroy($im);
?>

Thank you for the replies from Mission and Lemon-tree. I have been searching around for solution on that, but I found nothing. Thanks again.
