Files can be in the same category as other pages, but are treated separately: on the category page they are not included in the count of articles in the category, and they are displayed in a separate section, with for each a thumbnail and the name, see [[Help:Category#Category_pages|category page]]. A file category is typically a subcategory of the general category about the same subject, and a subcategory of a wider file category. On [[Wikimedia Commons]] there are essentially only files.
For categorizing a new file, the file page does not even have to be edited: the category tag can simply be put in the [[Help:Edit summary#File_upload_summary|upload summary]]. Many images can be categorized in one of the subcategories of [[:Category:Wikipedia Nordic Larp Wiki images by subject]]. You might need to poke around the category hierarchy a bit to find the right place.
