Does anyone know what is required to enable the GD graphics engine for
thumbnails other than to uncomment the dll line in php.ini? php info
reports the GD engine loaded, but nothing happens to to the images. On
the mediawiki site there was text about other lines to include in
LocalSettings.php (like the path to the convert command) but I cannot
find any file named "convert." Also there are references to two
ImageMagick lines to use in LocalSettings.php but nothing equivalent for
GD.
