This category will show all files that are missing a category, or has existing category/categories that need to be changed. It can also indicate that the picture is not showing up in one or more of its categories.
Categories may be added by clicking on Add category when editing the page. Put "adding category" in the edit reason (the Summary line next to Save page).
Categories may also be added while editing the page by manually typing the information, such as:
- [[Category:Phineas Flynn images]]
However, using the Add category button has the advantage that it will auto-complete categories for you and help you avoid typing mistakes.
When the categories are added or updated, remove the "Category needed" category from the page.
(Note: when the "Category needed" category was added to the file, sometimes this fixes the problem of not showing up in the categories. If so, just delete the "Category needed" category.)
