Show custom threadicon on forumdisplay

[TCB]

There's a modification for vb3.0 where you can add a custom theadicon (image) for selected forums (topic).

My whishes are a bit different though than the creator offered. So can anyone change the following code:

PHP Code:

 <if condition="$show['threadicons']"> 
        <td class="alt2"> 
        <if condition="$thread[forumid] == 7"><img src="http://www.mysite.com/images/forumdisplay/$thread[threadid].jpg" width="90" height="90"></if> 
        <if condition="$show['threadicon']"><img src="$thread[threadiconpath]" alt="$thread[threadicontitle]" border="0" />         
        <else />&nbsp;</if></td> 
        </if> 


in the threadbit template so that:

* images (named $thread[threadid].jpg) are shown instead of threadicons in forumid's 7,9 and 12 (for example)
* threadicons are shown in all other forumid's

With my alterations it works a bit (except for the conditionals), but threadicons (or an &nbsp) are also shown in the forums 7,9,12

Can anyone help me with these conditionals? Thanks a LOT
