I upgraded my Mediawiki Installation from 1.24 to 1.31.
After the update I see the message: "Fehler beim Erstellen des Vorschaubildes: Datei mit Abmessungen größer als 12,5 MP"
It means: the is an error at generating a preview image. The size of the image is larger than 12,5 MP
When I google around... the message is present in a lot of mediawiki installation around :)

Could someone help me out?
I solved it!
I installed imagemagick on my Ubuntu 18 with
sudo apt install imagemagick-6-common
and set imagemagick in the LocalSettings.php to
$wgUseImageMagick = true;
$wgImageMagickConvertCommand = "/usr/bin/convert";
3,456 * 5,184 = 17,915,904
If on windows, use Irfanview (ctrl-R) to downsize your image.
The Error occured in my installation with ImageMagick activated like described in LocalSettings.php.
MediaWiki 1.29.1 and imagemagick 6.9.7.4 in Debian 9.12
Same here. I still get: "Fehler beim Erstellen des Vorschaubildes: Datei mit Abmessungen größer als 12,5 MP"
my configuration is a follows:
MediaWiki 1.35, Linux CentOS 7 (checked with hostnamectl), ImageMagick 6.9.11-29 (checked with /usr/bin/convert --version)
$wgEnableUploads = true;
$wgUseImageMagick = true;
$wgMediaViewerOnClick = true;
$wgImageMagickConvertCommand = "/usr/bin/convert";
Solution / Lösung
LocalSettings.php
add $wgMaxImageArea / füge $wgMaxImageArea hinzu
i. e. / z. B.
$wgMaxImageArea = 2.5e7 ;
Creates thumbnails of images up to 25 Megapixels. / Erzeugt Vorschaubilder von Bildern bis 25 Megapixels.
