tensorboard: Auto-expand all images in Image tab?

[David Konerding]

Hi,

Apologies if there is a more specific tensorboard mailing list; I couldn't find one.

I am using the Images tab to evaluate many training images and their predicted objects.  It works well.  However, the page defaults to having only two open images with the rest hidden.  To view them I have to click on every one, and unless I click starting from the bottom image, I have to scroll and click to each new tab (if you start from the bottom image you don't have to scroll as much).

I can't find an option to default to more open images. I see this feature was explicitly added for resource issues: 

https://github.com/tensorflow/tensorboard/commit/942a25455e81af456db318aae591278c38aa5648

My system is not resource constrained, the main problem is that this default option of 2 images is a hardcoded constant:

At the very least, it would be great if this could be a command line flag or other configurable.
