Hi jgnerberry,
Welcome to Facer Community. It appears that you have a duplicate post in “Watchface Design”. I’ll do my best to give an answer.
As I understand the guidelines, you would either have to own the image/copyright/trademark, or you would need to have permission from the artist or brand to use their work here. That can also apply to images from so-called “free clipart” sites. Even some of those sites have received DMCA notices.
However, many artists will allow you to use their work if you ask and give credit to them in your description.
