auto watermark on images

[snark]

I found a terrific script that creates watermarked pics on the fly

what it does:

on opening an image it creates a new version of the image including the watermark

it does NOT edit the original and has the abillity to exclude files

for instance I told the htaccess file that files with relf in the filename do not have to get the watermark

in that way it works great with imageflow

how it is applied:

place the files in the attached zipfile in a dir in de media, alle the subfolders will react to the script

easy as can be

----

my question, it doesn't work with filenames that use spaces and that is something I like a lot in the imageflow

so I put in

Code:

Function Replace($image)
{

$pic = preg_replace('|[^a-zA-Z0-9_\-.]|', '-', $image);

return $pic;

}

but that does'nt do the trick

anyone?



note: you do not have to include any code into your files, just place the supplied files in de media dir

for everyone who doesn't know ... the htaccess in the zipp needs a dot before the filename as soon as it iss on the server...

does anyone know how to set the jpg quality for this... I want the jpg quality to be better than the huge compression it now automatically does...

Code:

<?php


$path = $_SERVER['DOCUMENT_ROOT'].$_SERVER['REQUEST_URI'];

$image = imagecreatefromstring(file_get_contents($path));



$w = imagesx($image);

$h = imagesy($image);



// You can change the watermark filename below.

$watermark = imagecreatefrompng('watermark.png');

$ww = imagesx($watermark);

$wh = imagesy($watermark);



imagecopy($image, $watermark, $w-$ww, $h-$wh, 0, 0, $ww, $wh);



header('Content-type: image/jpeg');

imagejpeg($image);

exit();

?>

The function imageJPEG has 3 parameters (last 2 optional).
The second parameter is a file to save the image (leave empty to use standard output)
The 3rd parameter is the jpg quality (1 to 100).

imagejpeg ( $image , '' , 85 ) ;

should output the image in jpg quality 85.

Edit: http://www.php.net/imagejpeg - The default quality is 75.

Hi guys,

Nice script. Works fine but I have two questions. Is it possible not to show the watermark.png itself in the gallery (I'm using Lightbox2) and secondly: I can't seem to manage not to let the watermark show on the thumbs.
This is what it says in the htaccess:

Code:

RewriteCond %{REQUEST_FILENAME} !thumb

Any ideas?

place a folder inside the folder where the watermark script is..

the watermark script also works on the subfolders.. that way you can point your lightbox module to a subfolder and not show the watermark.png

/media
/fotoalbums
  /- watermark script
  /- watermark.png
  /- subfolder
    /  - picture.jpg
    /  - picture2.jpg
    /  - picture3.png


lightbox - dir : media/fotoalbums/subfolder/

voila

What do you mean by 'file names'?

I recently have build this into A brax highslide gallery and that works fine
