PHP Exception while trying to generate Thumbnails for jpg extensions

Dear Douglas,

currently I notice on some articles (depending on category) some strange Error, which is indicating the plugin is trying to call a php function that does not exists (but imagecreatefromjpeg does!):


call_user_func(): Argument #1 ($callback) must be a valid callback, function "imagecreatefromJPG" not found or invalid function name

administrator\components\com_irelated\src\Helper\ImageHelper.php

My System:

• Ideal Related Articles 4.3.4
  Joomla 4.3.4
  PHP 8.1.22

I am not sure which change in my System had trigger this exception. But I can confirm that we have some images with the file Extension jpg and not jpeg. They should handled the same way.

Kind regards,

Markus Bruhn
