I am trying to display ads through out a network that

I am trying to display ads through out a network that is not setup like a MU. I think I have figured out 2 different ways to execute on this but was hoping staff could touch on the differences and pros and cons between each. I am essentially trying to display banner adds for our customers that login to their wordpress instance to edit content or anything else they might do on the backend. I would like the banner to be at the top of every page.

#1 - Use https://premium.wpmudev.org/project/admin-panel-tips/ ; I could use this and use html code to display a banner ad. What pages of the backend dashboard will it be displayed on and is this something that will be effective for what I am trying to do?

#2 - Use https://premium.wpmudev.org/project/admin-message/ ; Similar to above, can images be displayed in the form of a banner ad. I ideally want it to be displayed like the edublog ads on that link example.

Thoughts on what would be the best?
