In the LocalSettings.php file, $wgUseImageMagick is set to true. This did prevent GD from working on my MediaWiki installation (on XAMPP with Windows). Changing this one line did solve the problem for me: $wgUseImageMagick = false; From the documentation: PHP now comes with GD enabled by default. This will work for thumbnailing, and will not require any configuration or modification. Therefore it's highly recommended to not install ImageMagick, since it is known to be unstable. In fact the $wgImageMagickConvertCommand and Image.php mentioned below does not exist in MW1.15.1 https://www.mediawiki.org/wiki/Manual:Running_MediaWiki_on_Windows#ImageMagick I added the information to the documentation, however it would be really good if the MediaWiki installation "out of the box" would work without having to change this setting.
