Manual:$wgUploadPath

Details
The URL of the upload directory, relative to DOCUMENT_ROOT. This is used to construct URL for viewing uploaded files.

Note: $wgEnableUploads is commented out by default. Also remember to set directory permissions.

To enable permission checks on image files, $wgUploadPath can be pointed to the img_auth.php script - see Manual:Image Authorisation for instructions.


 * There are other variables which are defined relative to this one. If you redefine this in your LocalSettings.php then all dependent variables including wgUploadDirectory will need redefining also. If both these settings are not coherent the files will be uploaded to different folder  than from where MediaWiki will try to retrieve it for viewing !
