Hello, so i was trying to create an image when i tested the page on chrome, nothing happened, on firefox it gave me the error "the image blahblahblah' cannot be displayed because it contains errors, i thought my coding was the problem, so i went to php site and grabbed the simplest example i had:

$im = imagecreatetruecolor(120, 20);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);

// Set the content type header - in this case image/jpeg
header('Content-type: image/jpeg');

// Output the image
imagejpeg($im);

// Free up memory
imagedestroy($im);

and put it in my page, still same errors and here's the phpinfo output about GD: in the attachment.

now how can i debug this situation? btw when i remove the header content type, i get the JPEG header (in text) and a bunch of weird characters, any help?

Edit: i tried to save the image into a file and it's saved correctly, so why it isn't displaying in any browser?

If you add this to the top of the page, to enable all error reporting:

ini_set('display_errors', true);
ini_set('html_errors', false); // So they won't be HTML formatted.
error_reporting(E_ALL + E_NOTICE);

And then run the code using a Cotnent-type: text/plain header instead of the image content-type, what exactly is printed? Are there any error messages in the output that this generates?

Have you made sure there are no white-spaces before the opening PHP tag? (Easy to overlook.)

no errors, it displays the binary data of the image, as i said i tried to save the image in a file by switching

imagejpeg($im);

to

imagejpeg($im, 'filename.jpg');

and it saved a handsome image, the problem is why no browser wants to display my image directly in the browser or by using

<img src="thatfile.php" alt="some alt" />

it's just shows a broken image

Ok. There is something else being printed, though, otherwise the browsers would show the image.
Only other alternative I can think of is some odd server problem. Perhaps a compression bug. (Unlikely, though.)

Could you post the whole code here? In fact, it may help if you posted the file itself here. Things like Unicode BOM chars commonly cause problems like this, which would not be immediately apparent in editors that read Unicode files correctly.

You code works just fine on chrome and firefox both.

Edit, thank you so much that's what was the problem
