Tensorboard: Image scroll slider: only 10 positions

[Belerafon]

When I use slider at Image tab to scroll my images it is not possible to show all saved images: only 10 steps works. I think it because slider to scroll images has only 10 fixed positions. It must be able to scroll over all saved data. May be additional buttons like "step forward" are needed.

As we describe in the README, TensorBoard downsamples data to preserve memory usage. You should apply the following patch if you want TensorBoard to retain more images:
