Unit Header - how to add

How will the unit header be added to each site? Currently in D7 we have a place to upload a transparent png to the site. We'll need to be able to upload one for tablet, desktop and wide desktop as well as a second version for mobile.
Comments:

• hard coded imgs into header.twig
• utilized onerror img event and jquery to hide img and link if osu logo is not present in file structure (Brian Canini - Aug 13, 2018)
• The mobile logo is not showing. I think @briancanini mentioned that it needed to be uploaded. (Eva Dale - Aug 14, 2018)
• added Views Bulk Operator module and new field to Files view
• this allows admin to delete files after media entity has been deleted https://www.drupal.org/project/views_bulk_operations (Brian Canini - Aug 23, 2018)
