Delete Windows 8.1 Account Picture

It should be as easy as deleting the picture, but it's not... nothing is as easy as it should be in this train wreck. How do you delete an old account picture? I've tried just replacing it, but that turns into a whole puzzle you need to unravel first. If you pick the picture you want to replace, you would think that you would make it the big one of the 3, but you'd be wrong... that would make too much sense. If you hit browse and pick a new picture, the big one moves to the right and the new picture becomes the big one. Eventually you end up with 3 pictures and you get stuck in a sort of Rubic's Cube just trying to get the picture you want. This is some really bad software. Even the most die-hard M$ defenders have to know it, whether they want to admit it or not. So... how do you remove all the old pictures and only have the one you want.
