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