Watermarking Picture Problem

Post by adsegzy »

Hello,

I uploaded some pictures on my website and i want to watermark them on preview. the watermark file is

Code: Select all

<?php
// Load the stamp and the photo to apply the watermark to
$stamp = imagecreatefrompng('images/watermark.png');
$im = imagecreatefromjpeg('imgs/products/picture.jpg'); //needs to be dynamic instead of static

// Set the margins for the stamp and get the height/width of the stamp image
$marge_right = 10;
$marge_bottom = 10;
$sx = imagesx($stamp);
$sy = imagesy($stamp);

// Copy the stamp image onto our photo using the margin offsets and the photo 
// width to calculate positioning of the stamp. 
imagecopy($im, $stamp, imagesx($im) - $sx - $marge_right, imagesy($im) - $sy - $marge_bottom, 0, 0, imagesx($stamp), imagesy($stamp));

// Output and free memory
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>
with the line 4 above, where the picture is being specifies [$im = imagecreatefromjpeg('imgs/products/picture.jpg');], it displays the picture with the watermark perfectly.

Now i need this script for dynamic pictures. I have query the picture from the database and store it to $pix. but by replacing 'picture.jpg' with a string $pix, its giving me error, what can i do, or is there a better watermark code?

Thanks

Could you perhaps be a bit more specific?

what i mean is that, instead of the picture to come up with the watermark on it, the whole page is blank. But if i remove the script, the page will load all its content properly.
thanks
