I just can't seem to find an answer to this.
Normally I assign MIT License to all of my GitHub repositories, but so far they have only included code that I have personally written. I think that MIT License is great, but with my new project I need to include the logos of a few organizations. I have the permission to use these organizations' logos and digital brand images, but I clearly can't place these under the same MIT License as my code.
What license should I use for a repository that includes MIT Licensed code and trademark/copyright protected images like logos and brand imagery from third parties?
