проблем с GD

Рзползвам Linux, Apache/1.3.27, PHP/4.3.1
Когато използвам
--------------------------------------------------
$srcImage = ImageCreateFromJpeg( $imgFile );
...
$destImage = imagecreate( $destWidth, $destHeight);
ImageCopyResized( $destImage, $srcImage, 0, 0, 0, 0, $destWidth, 
$destHeight, $srcWidth, $srcHeight );
header("content-type: image/jpeg");
ImageJPEG($destImage);
--------------------------------------------------

Получената картинка изгежда като минала през филтър.
Много ще съм благодарен ако някой може да помогне.
Същото под windows работи без проблеми.
