Find out what the css class or name of the element you want to change. I believe the element you want to change has the class "tcat", but this class is also assigned to other headers, so if you change that you will end up having this image on other places aswell, not just where you specify you want it.

To resolve this you could give the element another class by adding it to the class value of the element. This would look like this:

<td class="tcat customback"

would replace

<td class="tcat"

The css would look like this:

.customback { 
	background-image: url('/images/customback.jpg');
}

I believe the template you are looking for is called: forumhome_forumbit_level1_nopost
