How to show IPTC field "Copyright Info URL" in category view?

Hi,
in  my photos I have stored information about the author's website in the IPTC field "Copyright Info URL".
Now I want to import this information into Piwigo and show the website url in the category view.
I have set up an example page here: http://piwigo.i-flora.com/index.php?/category/1

I finally found out how to import the IPTC data. But how can I show this information in the category view?
It would be great to have some variable like {$thumbnail.URL} in my template thumbnails.tpl
Regards
Ralf

Piwigo version: 2.10.2
PHP version: 7.3.10
Piwigo URL: http://piwigo.i-flora.com

Re: How to show IPTC field "Copyright Info URL" in category view?

Okay, I found out that the variables for the template thumbnails are defined in include/category.default.inc
By adding  'AUTHOR'=> $row['author'] to the array $tpl_var the copyright link (which I stored in the field author) is assigned to the smarty variable {$thumbnail.AUTHOR}, which I can use in thumbnail.tpl.

$tpl_var = array_merge( $row, array(
    'TN_ALT' => htmlspecialchars(strip_tags($name)),
    'TN_TITLE' => get_thumbnail_title($row, $name, $desc),
    'URL' => $url,
    'AUTHOR'=> $row['author'],
    'DESCRIPTION' => $desc,
    'src_image' => new SrcImage($row),
    ) );

I know, I shouldn't alter the Piwigo source code. How can I add this definition in my own plugin?
Thanks for any hint.

Thanks for your hint.
Meanwhile I found out, there is no need to define a new $author variable as the variable  {$thumbnail.author} already exists in the template thumbnails.php

Anyway, defining a new variable - i.e. {$thumbnail.CUSTOM} - for the template thumbnails.php can be done like this.

1. LocalFiles Editor > Personal Plugin
2. Insert
<?php
/*
Plugin Name: Personal Plugin
Version: 1.0
Description: Personal Plugin
Plugin URI: http://piwigo.org
Author:
Author URI:
*/

add_event_handler('loc_end_index_thumbnails', 'add_thumbnail_variable');
function add_thumbnail_variable($tpl_thumbnails_var)
{
  foreach (array_keys($tpl_thumbnails_var) as $id)
  {   
     $tpl_thumbnails_var[$id]['CUSTOM'] = 'My custom variable';   
  }
 
return $tpl_thumbnails_var;
}

3. Activate Personal Plugin
