+Tags a Docker image with a new name and tag. This operation is local to the Docker environment and does not involve network communication with a registry.
 
 # Arguments
-- `image_name::String`: The existing name (and tag) of the Docker image to be tagged. This is the source image name.
-- `new_image_name::String`: The new name (and tag) to apply to the image. This name can include a new registry path, repository, and tag.
+- `image_name::String`: The name of the Docker image to be tagged. This does not include the tag of the source image.
+- `old_tag_name::String`: The existing tag of the Docker image to be tagged. This specifies the exact version of the `image_name` to be used.
+- `new_image_name::String`: The new name to apply to the image. This name can include a new registry path and repository but does not include the tag.
+- `new_tag_name::String`: The new tag to apply to the image. This specifies the version of the `new_image_name`.
 - `auth_token::String=""` (optional): While tagging typically does not require authentication, if this function is part of a broader workflow that includes registry interaction, an auth token can be specified.
 
 # Behavior
-- Applies the `new_image_name` to the image identified by `image_name`. If the operation is successful, the image will be available under both the old and new names/tags.
+- Applies the `new_image_name` and `new_tag_name` to the image identified by `image_name` and `old_tag_name`. If the operation is successful, the image will be available under both the old name/tag and the new name/tag.
 
 # Example
-> image_name = "myimage:oldtag"
-> new_image_name = "myregistry.com/myimage:newtag"
-> tag_image(image_name, new_image_name; auth_token="my_auth_token")
+> image_name = "myimage"
+> old_tag_name = "oldtag"
+> new_image_name = "myregistry.com/myimage"
+> new_tag_name = "newtag"
+> tag_image(image_name, old_tag_name, new_image_name, new_tag_name; auth_token="my_auth_token")
 
 This example retags `myimage:oldtag` as `myregistry.com/myimage:newtag`, potentially preparing it for pushing to `myregistry.com`.
