True, but if the user was trying to recreate under the same name, that would stop that. If not, then there's nothing really you can do unless you can create some sort of companion program which analyses all images and sees if they match the one you don't want, which sounds difficult. There's no feature on Wikia which does that for you that I know of to prevent people re-uploading images under different names.
