Adding an icon for a user community in Oracle Information Discovery can done exclusively using functionality under Control Panel. However, in many cases the icon you want to add is larger than the size provided in the default Endeca theme. The steps below show how to modify the Endeca theme to accommodate a larger icon.
1. Change the icon under Control Panel -> Communities -> Manage Pages (of your selected community) -> Settings then click on the Logo tab. Select your file, check Use Logo and then Save.
2. Go to your Community and look at your banner. Your image may be cutoff if it was larger than the defaul “Oracle” image. You made need to adjust the size of the Endeca theme to accommodate a larger image. Notice below how the Oracle image invades the text and black bar.

5. Restart your Studio service to pick up your changes. You may need a few iterations of making changes and testing to get the sizes exactly what you want. Remember to restart the Studio service have each change.
