It depends on the license the picture was originally under or was uploaded under. If it already exists elsewhere (e.g. it's a film screenshot, book scan, other image), you need to find the original license and follow its terms. If an image only exists on Wikia or it was the first place to be uploaded into, check the file description page for info (click the image and click the filename in the lightbox).
