Manual:$wgEnableUploads/pt

Detalhes
Found in the LocalSettings.php file, when set to, users will be allowed to upload images and other enabled files. Users will see an 'Upload file' link appearing in the toolbox on the bottom-left (usually), linking to the Special:Upload page. This link appears for users with the 'upload' (logged-in users by default).
 * field there in Special:Upload page is a case sensitive field and should be used to give descriptive filename instead of using the default one populated from source file name.
 * If a file already exists in the system with name, uploading this file without changing   will create a archive file and store the older version in   folder.

IMPORTANTE: os envios precisam de ser configurados devidamente para serem seguros! Existem várias definições de configuração relacionadas. Recomenda-se que leia as instruções mais completas em
