Although the pictures have the GPS information enabled automatic synchronisation (photo management page) fails with the following warning:
Warning: Invalid argument supplied for foreach() in /mnt/sda1/var/www/piwigo/plugins/exiftool_gps/main.inc.php on line 23
Several thoughts:
- For one album automatic geotaging has worked for others did not.
- manual geocoding with setting lat lon has worked.
- The logitude convention the the little helper text of the page is wrong. The correct sign is negative for west and not the other way around.
