Random Missing Thumbnails

Greetings

I am getting random missing thumbnails. It does not matter if I load my images via FTP or the web uploader page. Specs for the gallery are below.

Piwigo 2.9.5
Operating system: Linux
PHP: 7.1.28 (Show info) [2019-05-02 21:18:32]
MySQL: 5.5.5-10.2.23-MariaDB-cll-lve [2019-05-02 17:18:32]
Graphics Library: External ImageMagick 6.7.8-9


I tested the same photos on a second gallery that I have with a different host. The thumbnails appear correctly on that gallery. The specs for that gallery are below. The only major difference is the version of MySQL.

Piwigo 2.9.5
Operating system: Linux
PHP: 7.1.26 (Show info) [2019-05-03 09:03:35]
MySQL: 10.1.38-MariaDB-cll-lve [2019-05-03 09:03:35]
Graphics Library: External ImageMagick 6.7.2-7

Re: Random Missing Thumbnails

The fix to resolve the random missing images was to switch from "auto" to "gd" in the config_default.inc.php file. Excerpt from the file is below.

// Library used for image resizing. Value could be 'auto', 'imagick',
// 'ext_imagick' or 'gd'. If value is 'auto', library will be chosen in this
// order. If chosen library is not available, another one will be picked up.
$conf['graphics_library'] = 'gd';

The file path is <Piwigo installation directory>/include/config_default.inc.php  I accessed it via FTP. There may be other ways to make the change to the file.

I came across this solution by starting with the "[FAQ] My pictures don't appear!" found in the "Docs" tab of this site, then also found a forum post discussing a similar topic at https://piwigo.org/forum/viewtopic.php?id=24414&p=2 to where this fix was discussed.

This is a new issue for this gallery. Images displayed fine until yesterday evening. Is this problem something I should share with my web host? If yes, what exactly should I relay to them?
