As long as they are clearly designated (Protip: Use categories) and follow all the other rules, images for guides are fine as those count as articles. Using that as a loophole, however, is not going to fly (Not that I think you would, but just throwing it out there for anybody who gets ideas.)

This is mostly going into place because there's literally hundreds of random images that have been uploaded to the wiki and have never been used. It would be a much better to only upload things that will actually be used in articles (and therefore be relevant to the wiki) and refrain from uploading anything else to prevent clutter. This includes images just being shared on the forums -- it's much better to upload the image onto a host such as imgur and share a link.
