This would be SO wonderful.
I use a chrome extensions called Exif Viewer that is REALLY good, it shows histogram and all the data possible from the image:
Bad thing there is no exif when you upload a picture to discourse… and I would have to tell the people from my forum to install the extension.
But it would be really nice to do something similar, for example in the lightbox, or maybe throught a plugin.
Or at least remove just the location from a security perspective, but the rest is really important!
