示例1: rmImages

	done := 0
	errors := 0
	staleErrors := 0
	imageMap := make(map[string]string)
	imageCounter := make(map[string]int)

	for _, pkey := range images {
		errors++
		h, err := types.NewHash(pkey)
		if err != nil {
			var found bool
			keys, found, err := s.ResolveName(pkey)
			if len(keys) > 0 {
				errors += len(keys) - 1
			}
			if err != nil {
				stderr.Error(err)
				continue
			}
			if !found {
				stderr.Printf("image name %q not found", pkey)
				continue
			}
			for _, key := range keys {

	}

	// Adjust the error count by subtracting duplicate IDs from it,
	// therefore allowing only one error per ID.
