Can I use things created by other people in my submissions?
Our copyright policy, in brief, states that your submissions may only contain materials or images which were created entirely through your own effort, authorized stock or resources and materials or images for which you have obtained permission for use in the submission.
This means that content such as screenshots, celebrity photographs, video game sprites, and other similar materials are not typically considered to be valid resources for use in submissions to your deviantART gallery unless you have obtained written permission from the copyright holder.
Failure to obtain proper permission for the use of materials protected under copyright can leave your deviantART submission vulnerable to being removed by our staff following a valid claim of infringement against it.
