Make the tiny "thumbs up" and "thumbs down" icons a little bit larger and easier to distinguish

In relation to the full screen for  Firefly, the "thumbs up" and "thumbs down" icons are miniscule and their yellow color does not stand out well against their white background.

I just generated some images and rated them with the tiny icons, and I think I clicked on "thumbs down" when I meant to choose "thumbs up" because it is very hard to distinguish between the two icons.

Make them a bit larger, please, and change the coloring so that they have better contrast to the white background. You will get more, and more accurate, ratings from us beta testers.
