Toggle Off Sprite on Embedding Projector Plugin

Hi Tensorboard team!

I am currently working on a project where I visualize the embedding on holdout set (think of MNIST dataset or CIFAR 100) to verify that our models indeed group similar items together. Currently I am using the plugin (i.e. saving the embedding data to checkpoint and visualize it via command line tensorboard --logdir logs, instead of uploading data to http://projector.tensorflow.org/).

I was able to attach sprite to the datapoint and sometimes it looks good (especially with smaller dataset), but when we try to visualize more points, sprite image actually make the embedding projector looks very clustered and just points would look nicer. In those cases I could have go into the configure file and manually delete the "path to sprite image" to disable using sprite but I am wondering if there is a way to turn off sprite on the tool itself (i.e. a button that says "disable sprite"), if not, do you think it would be a good use-case to have?

I am happy to contribute if you feel this feature may be useful :)

Sincerely,
Shun Lin
