OK, try this: edit your header template (Styles & Templates => Style Manager => "Go" next to your style (or Default Style), header is under "Common Templates").

Find the section that looks like this:

<tr>
	<td align="$stylevar[left]"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></a></td>

and change it to look like this (add the part in red):

<tr>
	<td align="$stylevar[left]"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img style="width:100%" src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></a></td>

I think that should resize the banner image (I tried the HTML just on my computer but not actually using the template). But it leaves a small gap on the right, which I think this is caused by this part (which is just below the part we just looked at:

	<td align="$stylevar[right]" id="header_right_cell">
		<if condition="$ad_location['ad_header_logo']">$ad_location[ad_header_logo]<else />&nbsp;</if>
	</td>

Deleting the " " seems to get rid of the gap, but I have to admit that I don't understand why it's there in the first place (I guess because sometimes it will look different than a completely empty table cell). ("nbsp;" is a "non-breaking space", so it just looks like a space, but it doesn't get removed like a normal space would).

(Remember to scroll down to the bottom and press "Save" when you are done making changes, of course).

BTW, the reason I wondered if you really wanted to resize it is because I have a wide screen monitor and I was thinking that if the banner resized to fit the width, it would also be ridiculously tall and not look good. But I tried it and it actually looks OK.
