Using a image for the Layout Border

I'm trying to add a border (using a gradient image) using ATO -> Style & Configure Layout -> Layout Container Style.

I've got some of it to work, but I cant get the image to go all the way around the layout.

I've also tried setting the image to a right side and a left side but the same image shows on both sides.

Here you will see the border on the left side is correct (a gradient blue) http://www.ffstock.com/blog/

Thanks in advance for any help and suggestions.
