Chat box title image

I'm helping a friend with her forum and we installed new Category titles. We placed the graphics in Background picture (Row title), Background picture (Row category left) and Background picture (Row category right). They show up fine everywhere but the chat box. How do we get it placed there also? I see no place for it. Is it a css code?
She's using Invision

Thanks Sanket but I tried every code there listed for Invision and none of them change the Background picture for the row title/category for the chat box..

For invasion you add chatbox header image here =>

Code:

#chatbox_header {
 background-image: url("YOUR LINK GOES HERE");

Since this thread is marked solved, I will lock this thread.
