Try changing the LinearLayout from android:layout_height="fill_parent"
(which I think may be meaningless when wrapped in a ScrollView) to
android:layout_height="wrap_content".

Or, switch from LinearLayout to RelativeLayout and anchor the ImageView
to the bottom via android:layout_alignParentBottom="true".
