You've basically got the right idea there. It works, but in a case like
that, Select Case would cut out the redundancy.

<%
showSub = Trim(Request.QueryString("subMenu"))
Select showSub
	Case "chinaHouseExpress"
		showImg = "expressSub.gif"
	Case "setMenu"
		showImg = "setMenuSub.gif"
	Case "starters"
		showImg = "saladsSub.gif"
End Select
%>
<div id="subHead">
<img src="images/<%= showImg %>" width="157" height="20" />
</div>

There's still only one visit to the server, but there is a processing hit
from having multiple code blocks. On a small site, it shouldn't matter, and
I have pages with three or four code blocks scattered through them. It might
make a difference of a few fractions of a second...nothing to worry about.

The Wrox book you have is one of the only ASP books I ever bought, along
with Wrox's ASP Databases. Those books cover just about everything. There
are more examples at:
