help:replacement notice (locked)
This feature allows you to replace the post's image with another image.
Replacements are meant for replacing posts with a better quality version of the same image. For example, fixing image samples, corrupted files, missing images, md5 mismatches, ugoira conversions, and so forth. They should not be used for non-identical images, such as revisions or variations of the same image, or for first-party duplicates (the same image uploaded by the artist to multiple sites).
Use the File or Replacement URL fields to specify the new image. Use the Tags field to add or remove tags after replacement.
See topic #16765 for further discussion.
