Network image loader, with local file system cache and in-memory cache
By default, using the static public methods will use an in-memory cache for 50 images and 4 megs total. The behavior of the static methods can be modified by setting the public DefaultLoader property to a value that the user configured. The instance methods can be used to create different imageloader with different properties. Keep in mind that the phone does not have a lot of memory, and using the cache with the unlimited value (0) even with a number of items in the cache can consume memory very quickly. Use the Purge method to release all the memory kept in the caches on low memory conditions, or when the application is sent to the background.
