Details

If you operate multiple wikis, you can define a shared upload path using $wgSharedUploadPath . If $wgUseSharedUploads is set, the wiki will look in the shared repository if no file of the given name is found in the local repository (for [[Image:..]], [[Media:..]] links).

If true, new subdirectory is created in /images folder (e.g. /images/a/ab/foo.jpg) for each file upload. If false, all images are uploaded in /images folder itself, see also Manual:$wgHashedUploadDirectory .

Set this setting to false especially if you have a set of files that need to be accessible by all wikis, and you do not want to use the hash (path/a/aa/) directory layout.

Setting this to true is equivalent to setting the hashLevels property in $wgForeignFileRepos to 2.
