To add a company logo to the banner, open the Configuration Panel in the Administration Module. On the Portal tab, add a URL to an HTML file or image file to the Customized banner URL field. You can also set the banner height by setting the Customized banner height value in pixels.
You can create your own HTML page that displays items such as your home screen logs, messages, announcements, web links, etc., and use this as the WorkflowGen banner.
