header('Content-Type: image/png');

$img = @imagecreatefrompng('christmas.png');
$font = imageloadfont('font.ttf');
$fontcolor = imagecolorallocate($img,255,255,255);
imagestring($img,$font,30,5,$countdown,$fontcolor);
imagepng($img);
imagedestroy($img);
    Code (markup):
    It returns an image that "Cannot be Displayed"

    You have to set the header after the php code
    this should work :

    


$img = @imagecreatefrompng('christmas.png');
$font = imageloadfont('font.ttf');
$fontcolor = imagecolorallocate($img,255,255,255);
imagestring($img,$font,30,5,$countdown,$fontcolor);
header('Content-Type: image/png');
imagepng($img);
imagedestroy($img);
    Code (markup):

    Make PHP tell you about everything on the first line "error_reporting(E_ALL);"
    Comment out the header() line
    Remove the error supression symbol (@)
    Look directly at the URL in your browser

    A lot of times what is happening is there is an error in one of the functions and the resulting image is currupted by the error messages.
