Ok, so I sort of have it working if I use the same header image with a fixed URL; BUT I want to have an 3 images named header.jpg that will be slightly different for each of my current 3 styles. This is what I have on my Default Header Includes that is not working:

HTML
<table class="t_inner" align="center" width="800">
<tr>
<td align="center" valign="middle" width="325">
<a href="http://YOUR_FORUM_URL/" target="_top">
<img src="{$config.BASE_URL}/images/{$style_array.general}/header.jpg" border="0" alt="FORUM NAME" width="500" height="100"></a>
</td>
<td align="center" valign="middle">

<!--// This gives you another column for ads, etc //-->

</td>
</tr>
</table>


Note my image URL. Unfortunately the {config.BASIL_URL| and the {$style_array.general} are not parsing (not being replaced with the actual directories for each style). The image location just stays as "{$config.BASE_URL}/images/{$style_array.general}/header.jpg"

What do I need to do to make this work?
