  <br>
  A null value will return null. Generally, this means the parameter was not present in the reply from Flickr.
  <br>
  A value of "1" will return {@link java.lang.Boolean#TRUE}. Any other non-null value will return {@link java.lang.Boolean#FALSE}.
  
  @param value the true/false value from Flickr.
  @return corresponding Boolean value, or null if value was null.
