You should now be familiar with creating, editing, and using categories in FatCat. You should be aware of two more options on the administration screen.
Some modules, like Announcements, make extensive use of the category icons. Sometimes you may want to supply a filler icon for a category. The Default Icon option will assist you. Just pick an icon you have on your computer or use one you have already uploaded. See Images and Icons above to see how to choose an icon.
Once you have selected your Default Icon, this picture will represent any category currently lacking an icon.
