+ * Phonebook 2 image commands are used to change contact image and thumbnail
+ * fields and operate on a locked store contact.
+ * Usually image field contains the filename of an original image and thumbnail field
+ * contains its scaled down binary version. It's possible that a contact has 
+ * only thumbnail field, e.g. when it was imported as vCard. 
+ * 
+ * All commands that return a MPbk2BaseCommand* handle may run asynchronously.
+ * The handle should be deleted to cancel the running command.
+ * 
+ * NOTE: Some command functions may return NULL, it is a valid value and means
+ * that command run synchronously.
