                    echo 'Porfavor <a href="'.$urlLogin.'">LOGUE!</a>';
                    error_log($e->getType());
                    error_log($e->getMessage());

                echo 'Porfavor <a href="'.$urlLogin.'">LOGUE!</a>';
            }
        ?>
    </body>
</html>

And this is what I get from that code, what should I do to fix this error?

    There are two problems with your code:

    1. On line 81, you’re outputting a content-type header. A single file can only output 1 content-type it’s either a HTML file or an Image file. More on this later

    2. On line 83, you’re trying to load an image from Facebook (imagecreatefromjpeg($foto_x);), which cannot be loaded. You’re only specifying the name of the image here (1100000000_x.jpg), without a directory or location, so PHP assumes is a local file and is trying to load a file that is in the same directory as the PHP script. I’m no familiar with the Facebook API, but I suspect that the image should be downloaded from their server, via HTTP, depending on your server settings this might or might not be allowed;

      $stamp = imagecreatefromjpeg(‘http://facebook.com/path/to/image/’ . $foto_x);

    Back to the first issue; It is not possible to output both an image AND the HTML in a single PHP script. One option might be to load the image from Facebook, manipulate it, write it to a file and use that as ‘src’ for the IMG-tag, for example:

    imagejpeg($im, $foto_y,100, '/full/path/to/mynewfilename.jpg');

    However, this will probably fill-up your server fast

    Another option is to split your script in two separate files;

    1) A file that outputs the HTML

    2) A file that generates the image

    This page will output the HTML and contains a IMG-tag that points to your image-generating .php page

    <!DOCTYPE HTML>
<html>
    <head>.....</head>
    <body>
        <img src='./my_super_image.php' /><!-- <<<< The name of your image script -->
    </body>
</html>

    This page will generate and output an image (only an image, nothing else)!:

    <?php
require_once("src/facebook.php");

.....

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

$stamp = imagecreatefromjpeg('http://facebook.com/path/to/' . $foto_x);
$im = imagecreatefromjpeg($moldeArma);
$marge_right = 20;
$marge_bottom = 330;
$sx = imagesx($stamp);
$sy = imagesy($stamp);
imagecopy($im, $stamp, imagesx($im) - $sx - $marge_right, imagesy($im) - $sy - $marge_bottom, 0, 0, imagesx($stamp), imagesy($stamp));
imagejpeg($im, $foto_y,100);
imagedestroy($im);                      
?>

    The code above is just for illustration, nothing has been tested!
