Can you explain why you set up the tests like that? It seems the test
is split over two files, with this change:
  +def imread_collection(x, conserve_memory=True):
  +    assert conserve_memory == False
  +    assert x == '*.png'
relying on a call from another file with the expected arguments. This
will be confusing I think.

The rest looks good to me.

Cheers,
