In the Azure DevOps dashboard, I need to add a static image. Is the MarkDown widget the simplest way to accomplish this? And, if that's the case, where do I save my image so that I can link to it in markdown? Also, could you provide me with an example? Is there a place on the dashboard to save photos or markdown files? Is it required to be saved somewhere in my git repository? I'd rather not because I'm only a scrum master and don't have easy access to a git repository.
