Step-by-step explanation:
Using creative work without the owner's permission is considered illegal and constitutes copyright infringement. This applies whether the work is shared with friends only or with the broader public, whether or not credit is given to the creator, and regardless of whether the work is changed or not. Copyright laws are in place to protect the rights of creators and owners of original works and to ensure that they are fairly compensated for their work.
