Manual:$wgImageLimits/fr

Détails
Cette variable contient un tableau de tableaux à deux éléments. Chacune définit une paire (largeur,hauteur) décrivant une taille maximale d'image (en pixels). The image sizes defined in this variable are used on the user preference page to allow the user to specify an image size-limit when viewing image pages. In order to reduce the amount of disk space taken up by thumbnails of many different sizes, limits can only be selected from this list.

This setting also determines the list of thumbnail links which are provided on the image page, just below the image.

Exemple
Si vous avez un habillage qui utilise une largeur fixe pour le contenu de la page, vous voudrez certainement que la taille maximale soit égale à cette largeur. Placez ces paramètres dans votre fichier.

If you change this array, you also want to change the default user option for image sizes on image pages. Each image size set is automatically associated with an integer value that may be used for the "imagesize" user option. This value always starts with "0" for the lowest image size set in the array and increases by 1 per additional image size defined, e.g. if five different image sizes were set the lowest value for the user option is "0" while "4" is the highest.
