I was looking for the Same info, and read many of the post here.
I tried many of the ways described, and this is what worked for me.
( I wanted to place the Banner on what was already there, for I wanted it to look like it's part of the Style)
Not Just a Banner "floating" above the Style/Forum.
To get this Look:
Here's What I did:
1) Create your Banner - make it 940px × 140px
Name it:
sitelogo_small.png - Then upload it to
/imageset Overwriting the one there (The Eagle).
2) File Edit
/imageset/imageset.cfg
FIND
img_site_logo = sitelogo_small.png*150*150
REPLACE
img_site_logo = sitelogo_small.png*140*940
3) File Edit:
/template/overall_header.html
FIND
<td align="center" valign="middle"><h1>{SITENAME}</h1><span class="gen">{SITE_DESCRIPTION}</span></td>
<td align="right" valign="top"> </td>
REPLACE
<!----------- <td align="center" valign="middle"><h1>{SITENAME}</h1><span class="gen">{SITE_DESCRIPTION}</span></td>
<td align="right" valign="top"> </td> ---------->
4) Go into your
ACP ( Administration Control Panel) Click on Styes tab, and Refresh Templates and Imagesets.
