Conditional masthead images/logos for different parts of a forum including threads?

[wcbryant]

I have a forum that covers multiple sports for a single university's athletic department. My normal title logo has a definite football theme. I've got one with a basketball theme, and would like that to appear instead of the football logo where appropriate.

I've managed to do enough reading and searching here and on vb.com to get it working on the forum view level. But when I go into threads within that forum, or the new thread page, it reverts back to the main logo, as if it doesn't recognize that I'm still within the basketball area.

Here's what I'm using so far. Note that on my board, 6 is the Basketball category, 7 is the Basketball forum. It shows up on both, just not down any deeper.

<if condition="$_GET[forumid]==6 OR $_GET[forumid]==7"><img src="path/to/basketball_logo.jpg" border="0" alt="$vboptions[bbtitle]" /><else />
<img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></if>

Any help/insight/suggestion would be greatly appreciated. To be clear, the goal is to have the alternate logo on all pages within forums 6 and 7, not just the forumdisplay pages.
