Ok Dennys. The change is done. Go to the url.

Ok now change 
$bg_color = imagecolorallocate($im, 255, 255, 255);
imagefill($im, 0, 0, $bg_color);
to this:
$bg_color = imagecolorallocate($im, 255, 255, 255);
if($bg_color === false || $bg_color == -1)
{
die('imagecolorallocate failed');
}
$test = imagefill($im, 0, 0, $bg_color);
if(!$test)
{
die('imagefill failed');
}

Ok now change 
$bg_color = imagecolorallocate($im, 255, 255, 255);
to 
$bg_color = imagecolorallocate($im, 255, 0, 0);

Then it should become a red box.
