White labeling the Logo (dynamic logo)

Does anyone know how to use ASPNETRUNNER to display a dynamic logo? I have several users, each with their own logo stored in a database table. I want to display the logo in the upper left corner of the screen when they login. I am not understanding how to use ASPNETRUNNER to achieve this. I already know how to do a static logo with an image stored as a file on the webserver. But I am not sure how to display a logo that comes from a database table.

Thank you
