You need to install and enable the php-gd image functions. On Ubuntu the
package is named
php7.4-gd
where 7.4 is your current active PHP version on the wiki.
In some cases you may need to enable it in your php.ini file, by
removing the initial semi-colon from the line:
;extension=gd2
You can see where is your php.ini by going to pmwiki.php?action=phpinfo
when remote diagnostics are enabled with $EnableDiag = 1;.
Then you may need to restart Apache.
See other cases:
