“ In addition, always tag a scanned or original image with {{original}} so that Commons users are aware that the image is not to be modified.
Categorization and galleries All images should be categorized and (in some cases) placed in galleries. A "gallery" is a page categorizing related images, so that a single work only appears once in a category instead of once for every image.
If a work contains many illustrations, it may be convenient to create a Commons category with that title; this allows the set to categorised by artist, author, and by subject matter. ”

“ Images that may have new editions in the future (for example, images used in regularly updated works such as the CIA Factbook) should include a version or year. For example, "Page 057 (CIA Factbook, 2007) .jpg". ”
