Found in the LocalSettings.php file, when set to
true, 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' right (logged-in users by default).
Destination filenamefield 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.

Destination filename, uploading this file without changing
Destination filenamewill create a archive file and store the older version in
imagesdirectory writable by the web server, otherwise you will just see an error such as
failed to open stream: Operation not permittedor
Could not create directory "mwstore://local-backend/local-public/0/00". Note that a web server writable directory is not insecure in itself, but can be thought of as the first half of a successful attack to your web server, as such you might like to explore alternatives using img_auth.php.
