title: Tensorflow : Enlarge images on Tensorboard embedding?
body: <p>The images on the Tensorboard embedding visualization are fairly small. 
  It's ok for MNIST, but not good for other real images.</p>
  
  <p>Even when I zoom in, the image sizes are not changing. 
  I tried to use larger sprite image size but it doesn't work as well.</p>
  
  <p>Is there a way to make it bigger? Thanks!!</p>
