Including option RotationAction->"Fit" almost works: the image stays of 
a fixed size EXCEPT when I finally release the mouse after rotating the 
image.

What seems to work better is option SphericalRegion->True.  The image 
remains the same size from its initial, static form through the rotation 
and beyond, after the mouse button is released.
