the contains is unnecessary, LastIndex already tells you if it contains or not so we only need to walk the string once not twice

index := strings.LastIndex(name, separator)
return fmt.Sprintf("%s%s%s", name[:index], separator, tagOrDigest)
}
return fmt.Sprintf("%s%s%s", name, separator, tagOrDigest)
