Details

The default settings for the ‎<gallery> tag, and galleries in categories.

See the "default value" below for the possible keys, and a description of each setting.

Some of these settings correspond, in a confusing way, to attributes that can be specified for the ‎<gallery> tag itself. See Help:Images#Optional gallery attributes for information on each of the attributes.

This key in $wgGalleryOptions...	...sets the default value for this ‎<gallery> tag attribute
imagesPerRow	perrow=
imageWidth	widths=
imageHeight	heights=
mode	mode= (New in MediaWiki 1.22 – see Help:Images#Mode parameter for more information)
