What is Copyright Infringement?
To simplify this question, copyright infringement occurs when you do certain things with a creative work which someone else produced without first getting the proper permission.
Some examples of copyright infringement (this is only a partial listing) can include:
- Placing someone else's photograph or creative work online without proper permission.
- Using a creative work commercially without permission.
- Adapting someone else's creative work found in one medium to another medium, such as making a book into a movie or a photograph into a painting.
- Modifying or editing a creative work without proper permission.
Remove all stolen images, the result of you not complying will result in a ban by Deviantart's head administration.
