My b2evolution Version: 1.9.x

Hey guys,

I have a problem, and I hope someone could help me with it.

I'm using the custom skin, and what I basicly want to do is add some more thin grey line separators between some "hardcoded" images I put in the sidebar.

Could anyone please explain how to do this?

Best regards,

Emile

Ps. I know that it's a background image, I just dont understand where it is, and how I can put it in. THANKS IN ADVANCE!
