 I'm not sure if this has been talked about before, but with FileReader we
 could preview images in the media modal.

 I've made a quick patch to try it, but it's far from perfect... It
 sometimes flickers and the reading seems to block js from executing
 further, so not ideal for uploading a ton of images at the same time.
 Still, I'm sure we can get this to work smoothly somehow.

 I'll attach a screenshot. I think this would be a really cool experience.
 :)
