Quick Help: Update Conditional Code to 4.0

[Phrost]

Hi, thanks for reading this.

I recently updated one of my sites to 4.0.8 (from 3.5.4) and it broke a nifty bit of custom code I had that displayed an icon for each forum on the forum homepage (using a simple "forumid#.gif" convention).

Here's the original code:

<a href="forumdisplay.php?$session[sessionurl]f=$forum[forumid]">
<img src="images/forumhome/$forum[forumid].gif" alt="" border="3" " align="left" /></a

Obviously, this doesn't work now. Any ideas what I need to change?
