As far as editing on Wikia goes, an important difference is that if you want to replace a JPEG with a JPEG or a PNG with a PNG, you can just choose to edit the existing file and tell it you're replacing it--then everywhere that file name is used will automatically use the new version. But if you want to replace it with a file of a different type, it means actually changing the page(s) where it's used--and so the change and comment left about why is more noticeable.
