You can either use a ContentObserver with MediaStore to find out when any images are added or removed, or you can use FileObserver to monitor the standard path to pictures on external storage.

Neither of these will necessarily reflect "Picture Taken", as camera apps do not have to store their images in that specific folder, nor do they have to have their images indexed by MediaStore.
