To change the logon image in Workspace
Edit the file logon_panel.gif. If you’re using Weblogic, you should find it under:
D:\Hyperion\deployments\WebLogic9\servers\Workspace\ webapps\workspace_webservices\workspace\themes\theme_tadpole\images_global
This is especially useful in LB environments where you need to know which server you are connecting to.
Restart Workspace web and voila
TIP: To help find this file, go to d:\Hyperion and search on ‘logon_panel.gif’. It’s usually the second to last file in the returned results.
