I created class:
class PersistableStore implemented Persistable{
private Hashtable encodedImages;
....
}

Hashtable keeps images and I am peristing PersistableStore object. But when I do it exception is thrown saing that EncodedImage is not persistable. How can I make it persistable?

You have to subclass from EncodedImage and implement Persistable as you did for PersistableStore. Any object you put in a persistable object must also implement persistable.
