Top and bottom images for widgets

Hi there!

On my site, http://fredsmythe.com, I just followed the directions in this thread for adding top and bottom images to my widgets in my sidebar:

...and for the most part it's working, which I am very very happy about! One problem, though, which you can see: the bottom three ones (with the dynamic content) have that teeny space between the bottom of the widget and the bottom image.

I would LOVE LOVE LOVE to fix this. Anyone have any ideas as to what I might need to edit to fix this?

Thanks much!
