Pages are added automatically to this category by placing the template {{BArch-image}} (with missing or empty parameter ID) on them. Do not add pages to this category manually! Maintenance: Search for misplaced files using PetScan (will not work on categories shared by many templates).
Since the parameter ID is added automatically to all images, the lack of it usually means that something else is broken in the template.
This category is a source category. This type of category can be added by template. It appears in the second line of categories.
