Watermarking

[micronicos]

I want to be able to upload a JPG and have GD place a watermark on all of the images as they are viewed (depending of speed of GD) or else creating a watermarked version and keeping the origional somewhere for me.?

Any ideas on the best way of storing the files, RAW then watermarking on the fly, ? or storing 2 versions.

All images will be uploaded and rezised to same size, have code for that, its just the watermarking bit?

WATERMARKING - not really, just logo in a corner.

Basically, this will add a logo to the bottom right corner of the image leaving a 10-pixel gap between the logo and the edge of the image.

<?php

define ('PADDING', 10);

$size[0] = getimagesize ('./myjpg.jpg');
$size[1] = getimagesize ('./logo.jpg');

$orig = imagecreatefromjpeg ('./myjpg.jpg');
$mark = imagecreatefromjpeg ('./logo.jpg');

imagecopyresampled ($orig, $mark, $size[0][0] - size[1][0] - PADDING, $size[0][1] - $size[1][1] - PADDING, 0, 0, $size[1][0], $size[1][1], $size[1][0], $size[1][1]);

?>

Once you've uploaded the image, you need to use variables instead of a straight file name to edit the image.

I would suggest doing it at upload because GD can be quite slow and server-intenseive doing it the other way. My suggestion would be to generate two files when the upload a file:

upload_x_original.jpg
upload_x_thumb.jpg
