An image that has been altered by the artist to make corrections to it. The changes may be minor (such as a missing mole) or they may be major (correcting for bad proportions, or adding censorship).
This tag should not be used unless there is a visual difference between the images. Images that differ only in resolution or compression level are duplicates, not revisions.
It also should not be used if the original non-revised image doesn't exist on Danbooru.
If a post was completely redrawn, use redrawn instead.
- md5 mismatch
- has bad revision (for when a revision is available, but it is inferior to the image already on Danbooru)
- has censored revision (for when a revision is available, but has been censored, most likely due to the artist accidentally posting an uncensored version)
