so what are you wanting to do ..is it just a static image or what ? and per forum ID you want the image to change ? actually that would work or you could put in array like this
Code:
<vb:if condition="in_array($GLOBALS['forumid'], array(1,2,3,9,10))">
<div align="center"> <img src="images/banners/{vb:raw $GLOBALS.forumid}.png" align="center" alt="banners" border="0" /> </div>
</vb:if>
you would have to name your images the same as the forum id .png
example
forum id 1
1.png
