[ondoy]

hehe naa bro.
- kini nga lines:
$watermark_width = imagesx( $watermark );
$watermark_height = imagesy( $watermark );

error ani ky ang e accept sa imagesx() ky resource,ang imo gi pasa ky boolean.

- pwede mnka sugod lngsa ginagmay lngsa ayaw e dungan.try ni sa php manual nko ni gi kuha:
<?php
function LoadJpeg($imgname)
{
/* Attempt to open */
$im = @imagecreatefromjpeg($imgname);

/* See if it failed */
if(!$im)
{
/* Create a black image */
$im = imagecreatetruecolor(150, 30);
$bgc = imagecolorallocate($im, 255, 255, 255);
$tc = imagecolorallocate($im, 0, 0, 0);

imagefilledrectangle($im, 0, 0, 150, 30, $bgc);

/* Output an error message */
imagestring($im, 1, 5, 5, 'Error loading ' . $imgname, $tc);
}

return $im;
}

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

$img = LoadJpeg('bogus.image');

imagejpeg($img);
imagedestroy($img);
?>
