Do we want an ubiquitous image template as part of the library?

See for detail discussion.

If you have worked with matlab or openCV, I surly think you will remember lenna.png. It is an ubiquitous test image thats embedded in the library, and you can invoke it without any network or external disk dependency.

I am proposing adding such an image to the library. This will be helpful in reproducing and highlighting data augmentation transform bug. So it may be a narrower use case.

Just putting it here to get more general feedback.
