line 25 replace thumb by square

Hello...

I think this is close to what I need, I found this in a search so here I start....

My info FWIW:

Piwigo version:  2.7.4
PHP version: 5.3.29
MySQL version: 5.5.45-MariaDB
Piwigo URL: http://true-grit.org/piwigo

I am looking to display a 1 random thumbnail on another web page, in a Tinyportal 'block' on a SMF forum . I've used other galleries and was able to display a random thumbnail, but am new to piwigo.

I tried the codes here edited, I'll post one below that I edited as maybe I made a mistke, but mostly I think that the code is not quite right, but am not sure why. You can see the gallery block here, on the right side. Nothing fancy just a random thumbnail from an SMF gallery.

Here is your code I edited:

<?php
$base_url = 'http://true-grit.org/piwigo/ws.php?format=php&method=';

$url = $base_url.'pwg.categories.getList&recursive=true&public=true';
fetchRemote($url, $result);
$result = unserialize($result);
$albums = $result['result']['categories'];

foreach ($albums as $idx => $album) {
  $date_last[$idx] = $album['date_last'];
}

array_multisort($date_last, SORT_DESC, $albums);
$albums = array_slice($albums, 1, 1);

echo '<table><tr>';
foreach ($albums as $album) {
  $thumbnail_url = $base_url.'pwg.categories.getImages';
  $thumbnail_url.= '&cat_id='.$album['id'];
  $thumbnail_url.= '&per_page=1';
  $thumbnail_url.= '&order=random';

  fetchRemote($thumbnail_url, $result);
  $result = unserialize($result);
  $thumbnail_url = $result['result']['images'][0]['derivatives']['thumb']['url'];
 
  echo(
    sprintf(
      '<td><a href="%s"><img src="%s"><br>%s</a></td>',
      $album['url'],
      $thumbnail_url,
      $album['name']
      )
    );
}
echo '</tr></table>';
