thank's for help, but here https://commons.wikimedia.org/wiki/Commons:First_steps/Upload_form I read that to upload contents the users must be logged, so how can I manage the upload without a login?
You can't. You need to create an account in Wikimedia Commons [1] in order to upload a file there. If you already have an account at another wikimedia site (eg. it.wikipedia), just use your user and password and it should work.
