graphs: cannot be displayed, becuase it contains error

[jrumpf]

Just posting this hoping those who get this message in firefox when trying to display graph images will see it:

The image cannot be displayed, because it contains errors.

Took me two hours to track the issue down. Ended up, I had an extra newline line after the closing php tag in zabbix.conf.php.

$IMAGE_FORMAT_DEFAULT = IMAGE_FORMAT_PNG;
?>

<EOF>

That newline was being echoed back to the browser for every image. Thus, confusing Firefox. Removing the newline made everything work as advertised.

Thanks,
Jeremy
