Aligning my image to bottom of footer and centered

hi Ive been trying for hours to find a way to align an image at the bottom of my footer and have had no luck.

As you can see on my site https://www.wisewonky.com/wordpress/

there is a border gap at the bottom which i can’t get rid of! Its been driving me nuts all day!

Ive been trying to use firebug to fix it but i can’t see the problem.
If there is a way to get rid of that space underneath the image at the bottom I would appreciate a point in that direction.

Please help!

Chimpulous ??
