The usage of watermarks is discouraged according to policy. If a non-watermarked version of the image is available, please upload it under the same file name, and then remove this template. After removing the watermark, ensure that the removed information is present in both the EXIF tags and the image description page, and add either the {{Metadata from image}} or {{Attribution metadata from licensed image}} tag.

If the old version is still useful, for example if removing the watermark damages the image significantly, upload the new version under a different title so that both can be used (e.g. [[Image:Mount_Everest.jpg]] → [[Image:Mount_Everest - no watermark.jpg]]. After uploading the non-watermarked version, replace this template with: {{superseded|Image:Mount Everest - no watermark.jpg|image without watermarks}}, replacing the italicised name with the file name in question.
