Please close this topic. I solved the problem. I happened to read Mikem's old forum thread about header top table split into 2 columns in all nukemods themes (left is for the logo & the right is for the banner).
How do I center banner?
Since I know now that the banner column is the one I should remove, I've added adverts (
//) to it but it doesn't solve the problem.
//<td width="40%" height="85" align="right">$showbanners </td>//
The solution is to remove the [ ] so it would look like this script below...
<td width="40%" height="85" align="right">$showbanners</td>
For smaller logos, removed the entire showbanners script & add additional codes to center your logos.
