The Gallery is full of thousands of images of free art. The images have no copyright, so you can do whatever you want with them, except you cannot claim that they belong to you or copyright them yourself.
Currently, because we don’t feel like going to court, and because there’s plenty of porn already on the internet elsewhere, it isn't permitted, although that could change in the future if we implement an age verification option.
Galleries are public, but if you wish to contribute or rate, you can create an account and upload images under the community gallery; just make sure that they fit these two standards: not pornographic, and not copyrighted).
