At times, it may be desirable to remove Images from the cache. This can become particularly important if the application is about to do something memory-intensive, or if the developer knows that a certain Image will not be needed again for a long period of time. The nUIController class provides additional static methods to clear the Image cache. nUIController.clearCache() removes all images from the Image cache. nUIController.clearCache(String) will remove a single Image from the cache with the path and file name given to load it initially.
