**--scoped** Prefix images with the source image path, so that multiple images with the same name can be stored at _destination_.
**--append-suffix** _tag-suffix_ String to append to destination tags
**--preserve-digests** Preserve the digests during copying. Fail if the digest cannot be preserved. Consider using `--all` at the same time.
**--remove-signatures** Do not copy signatures, if any, from _source-image_. This is necessary when copying a signed image to a destination which does not support signatures.
