Ok I figured out a way to make the images directory work anywhere you potentially call it.
Original
<a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="images/epic/header_left.gif" width="250" height="109" border="0" alt="" />
Update
<a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="
$vboptions[bburl]/images/epic/header_left.gif" width="250" height="109" border="0" alt="" />
I'd suggest updating the original zip, that way it will work regardless of the setup.
