Manual:$wgUploadPath/en

Details
The relative path to the upload directory. This is used to construct the URLs for viewing uploaded files.

In most cases this is just the path component, such as "/w/images". If uploaded files are served from a different domain, this can be a fully-qualified URL with hostname, such as "http://upload.wikimedia.org/wikipedia/en".

If the variable contains a local path (without "http://") then it must start with a slash, otherwise it will result in a bad URL. (For example if you set it to "foldername" it will result in files being loaded from " http://www.example.comfoldername " - note the missing slash after ".com")

To enable permission checks on image files, $wgUploadPath can be pointed to the img_auth.php script ( $wgUploadPath = "$wgScriptPath/img_auth.php"; ) - see for instructions.
