<? function watermark($SourceFile?, $WatermarkFile?, $SaveToFile? = NULL)

{

or exit('Cannot open the watermark file.');

imageAlphaBlending($watermark, false);

$imageWidth=imageSX($image);

$watermarkHeight=imageSY($watermark);

$coordinate_X = ( $imageWidth - 5) - ( $watermarkWidth);

if(!($SaveToFile?)) header('Content-Type: image/jpeg');

imagejpeg ($image, $SaveToFile?, 100);

imagedestroy($image);

imagedestroy($watermark);

if(!($SaveToFile?)) exit;

}

And after

$result = file_put_contents( $filename, file_get_contents('php://input') ); if (!$result) {

print "ERROR: Failed to write data to $filename, check permissions\n";

exit(); }

This code:

// The image should be located in a non public directory

$image_location = 'dir/test.jpg';

// Locate the watermark file wherever you choose (remember PNG format)

$watermark_location = 'watermark.png';

// Watermark the image and send it to the browser

watermark($image_location, $watermark_location, $image_location);
