What kinds of artwork and maps can I use in my DMs Guild titles?
The artwork (such as illustrations or maps) that you include in your title does not become part of the DMs Guild content that other DMs Guild contributors can then use. Here is general advice for these types of artwork:
Art and maps provided by Wizards of the Coast. The art you find in the Resources for DMs Guild Creators category is owned by Wizards and can be freely used in your DMs Guild titles. No other artwork from Wizards of the Coast titles can be used — only the art specifically released for DMs Guild Creators.
Public Domain Art. Art that you are certain is in the public domain can be used.
Stock Art. Usage of stock art depends on the license associated with that stock art. Most of the stock art sold under the DMs Guild Resources category on DriveThruRPG includes a license that would allow it to be used in your DMs Guild titles.
Commissioned Art. Usage of art that you commission from an artist depends upon your terms with the artist. You must have the rights or license to use the art in your title. The artwork does not become owned by OneBookShelf or by Wizards; you simply must have rights to use it in your commercial work.
Creative Commons. This depends on the type of Creative Commons license. Some allow commercial use, others do not.
Can I use the D&D logo on my DMs Guild title?
The only logo you can use in your title is the DMs Guild logo found here:
Custom logos and other variations of existing logos are not allowed
