You mean if you change from horizontal to vertical? Droid-Fu uses a two-level cache so it should handle this case relatively well: the bitmaps are weak-referenced and kept around if RAM permits, otherwise the disk is consulted. IMO, Android handles the whole orientation thing poorly. Destroying an entire activity because the orientation changed violates the principle of least surprise.
