Creating watermark on uploaded images --- PLS help

[kiwi]

Hi

I am trying to watermark all the images uploade on website. Using jpg image and watermark image is png24. I am using following code

photoImage = ImageCreateFromJPEG('photo.jpg');
ImageAlphaBlending($photoImage, true);

$logoImage = ImageCreateFromPNG('logo.png');
$logoW = ImageSX($logoImage);
$logoH = ImageSY($logoImage);

ImageCopy($photoImage, $logoImage, 0, 0, 0, 0, $logoW, $logoH);

ImageJPEG($photoImage,"newimg.jpg",75);

ImageDestroy($photoImage);
ImageDestroy($logoImage);


----

But new image is not created and ImageJPEG() return false.

Please any one can help me to identify what's the prob / what may be causing the prob ????

Thanks

The only problem that I can see is that you don't use header("content-type: image/jpeg"). I doubt that would be generating the error message that you describe though.
