Update: I find that in my system, the fix proposed by http://piwigo.org/forum/viewtopic.php?id=22796 is the one that works.

Hello,
Is still have this old issue with ImageMagic on Windows.

The fix provided aboves does not work as the second lines are differnt now:
Staring 491:

  function write($destination_filepath)
  {
    // use 4:2:2 chroma subsampling (reduce file size by 20-30% with "almost" no human perception)
    $this->image->setSamplingFactors( array(2,1) );
    return $this->image->writeImage($destination_filepath);
  }
}

I tried to add :
$destination_filepath = realpath($destination_filepath);
before
return $this->image->writeImage($destination_filepath);

When I run it I,  have errors in my apace log:  "Can not use empty string as a filename' "

Looks like there are still problems with the paths.
This was working for me but one of the last updates must have changed something.
Before the Modification porived above helped me.

Thanks in Advance for your support

I am running

Piwigo 2.8.1

But as mentioned Think it is not in image magic, but in Piwigo the path issue.
Using GD lib it is working ok now.

I know I am running some old stuff in there, but I do not believe that this is the issue... As it has been working before i did the upgrade and forgot about my modifications I did as advised here.

I guess the image class with the funciton:
Staring 491:

  function write($destination_filepath)
  {
    // use 4:2:2 chroma subsampling (reduce file size by 20-30% with "almost" no human perception)
    $this->image->setSamplingFactors( array(2,1) );
    return $this->image->writeImage($destination_filepath);
  }

has to be fixes for windows someHow that the paths are fine.

Thanks again for your Support!

Ok, lets see if there are more ...

Are there any know "ready to use" / preconfigures WAMP systems with image magic that work out of the box on windows? (doid not search until now... )

May be I will try do a migration than ... if that would solve my issue.

luckily the server is virtual :D

Thanks!  SOLVED!
Your modification did the job ....

Now I have to be carefull with updates.
So it is working with:
Betriebssystem: WINNT
PHP: 5.4.10 (Info anzeigen) [2016-10-08 12:37:08]
MySQL: 5.5.29 [2016-10-08 12:37:08]
Grafikbibliothek: ImageMagick 6.9.3-7
secure WAMP

I would like to confirm the directory separator worked for me in 2019 for a windows 2016 box utilizing xampp.

Piwigo 2.10.1
Operating system: WINNT
PHP: 7.3.10  [2019-10-31
MySQL: 5.5.5-10.4.8-MariaDB [2019-10-31
Graphics Library: ImageMagick 7.0.7-11

I was getting the PHP Fatal error:  Uncaught ImagickException: UnableToOpenBlob '././upload/2019/10/30/<blah>': No such file or directory @ error/blob.c/OpenBlob/3315 in
C:\\xampp\\htdocs\\piwigo\\admin\\include\\image.class.php:400\nStack trace:\n#0 C:\\xampp\\htdocs\\piwigo\\admin\\include\\image.class.php(400): Imagick->__construct('././upload/2019...')\n#1 C:\\xampp\\htdocs\\piwigo\\admin\\include\\image.class.php(72)

I tried the realpath fix from earlier posts and went that direction for a few hours. That was unsuccessful for the most part. Then tried sridharb's fix. Uploaded with same batch job i've been trying to do, and bam, it worked with thumbnails and images loading.

At this version for anyone else running into this, edit the file: image.class.php

at line 71 and 72 you will see:
    $class = 'image_'.$this->library;
    $this->image = new $class($source_filepath);
   
Comment out with //$this->image = new $class($source_filepath);
Add this line:
    $this->image = new $class(__DIR__ . DIRECTORY_SEPARATOR . '../../' . $source_filepath);

You will do this again at the 480 line and it should look similar to this:
    $this->image->setSamplingFactors( array(2,1) );
    //return $this->image->writeImage($destination_filepath);
    error_log("B: " . $destination_filepath . " A: " . __DIR__ . DIRECTORY_SEPARATOR . '../../' . $destination_filepath);
    return $this->image->writeImage(__DIR__ . DIRECTORY_SEPARATOR . '../../' . $destination_filepath);
