Add a Banner
To add a banner to your course:
On the Control Panel,
expand the Customization section and select Teaching Style.
Go to the last Section “Select Banner”:
Use Browse My Computer to locate an image file on your computer.
A recommended size for banners is approximately 480 by 80 pixels. When choosing a banner image, keep in mind that users can resize their browser windows, expand and collapse the course menu, and use monitors of varying sizes and screen resolutions. After you upload a banner, view it under those varying conditions to be sure that it appears as intended.
