An image containing text or a [[logo]] superimposed on top of the image. Typically to identify the owner/creator of the work and/or prevent the image from being counterfeited. Some watermarks are also deliberately placed as a "paywall" on "samples" of "[[paid reward]]" images.

Posts with watermarks added by [[third-party watermark|third-parties]] (anyone other than the artist) should not be uploaded.

Add [[watermark grid]] if it spans over a majority/the whole image. Add [[too many watermarks]] if it's in excess as to be noticeable from the thumbnail.
