Roger that.
But why does the thumbnail of this is black while the full view background of this is clearly white?

That's because of the transparent background and the way your browser renders that as a thumbnail.

I thought it wasn't the browser dropping the alpha in thumbnails but rather the image processing software used by Danbooru.
