Creating Images - format with html

ctheun

I`m able to create php generated png images, that seems to be the easy part.
--- code ---
<?
header("Content-type: image/png");

$text = "Image created by me";

$width = 500;
$height = 100;
$image = imagecreate( $width, $height);
imagecolorallocate($image,290,50,121);
$black = imagecolorallocate($image, 255, 255, 255);

imagettftext($image, 20, 0, 20, 60, $black, "/var/www/html/php/images/verdana.ttf", $text);
imagepng($image);
imagedestroy($image);
?>

That all works fine.
But when I try to indend html into it, the script bombs out and says :
The image “http://whale/deon/create2.php” cannot be displayed, because it contains errors.

This is the code i`m using.

<?
header("Content-type: image/png");
?>
<table>
<tr>
<td align="center">
<?
$text = "Image created by Deon Heunis";
$width = 500;
$height = 100;
$image = imagecreate( $width, $height);
imagecolorallocate($image,290,50,121);
$black = imagecolorallocate($image, 255, 255, 255);
imagettftext($image, 20, 0, 20, 60, $black, "/var/www/html/php/images/verdana.ttf", $text);
imagepng($image);
imagedestroy($image);
?>
</td>
</tr>
</table>

I`m stuck.
Thanks

That's because if you want to imbed images in an HTML page you use the <img> tag to supply a URL to the image - you don't stick the binary data of the image itself directly into the HTML file.

Contrariwise, when the browser sees a Content-Type of image/png, it's expecting to get a PNG file. If what it gets doesn't look like a PNG file it assumes the file is corrupted. And what it's getting from your script doesn't look like a PNG file, because PNG files start with "‰PNG", not "<html>". So obviously this "PNG file" is corrupted.

Put your image generation code in a separate file (call it "image.php", say), and then refer to it in the HTML as

Thanks...
So is it then one php page, one image???
What do you do when u have multiple images u want to create.??

Call the script multiple times.

If they've got different details, recommend adding a querystring to the URL

<img src="image.php?pic=something">
(taking into account rules regarding the format of URLs), and then in image.php looking at (in this case) $_GET['pic'] to see what image to produce.
