I am in favor of option 1.  I think option 3 still will allow our
users to accidentally use copyrighted imagery, while our policy is
that all images are freely redistributable.

The problem is that Lena was used to generate a whole bunch of
tests results in Matlab, stored as .npy files.  I no longer have
access to the script that generated those.  Looking at those tests
(mostly in the morphology submodule), I think it would be better
if we could re-engineer the tests to look at image properties,
rather than to compare them pixel-for-pixel to MATLAB results.
Doing that will require some work.
