I am trying this because IE likes to cache graphics and we can't seem to force
it to let go. It doesn't seem to work.
Is there a way to tell IE to expire the graphics it takes without telling users
to clear temporary internet files or renaming graphics?

Something like this (shared by another cf-talker some time ago):
Put this after the </head>:
<CFHEADER Name="Expires" Value="Sun, 06 Nov 1994 08:49:37 GMT">
<CFHEADER NAME="pragma" VALUE="no-cache">
<CFHEADER NAME="cache-control" VALUE="no-cache, no-store, must-revalidate">
... or the paranoid version:
<CFSET gmts = gettimezoneinfo()>
<CFSET gmt = gmts.utcHourOffset>
<CFIF gmt EQ 0>
<CFSET gmt = "">
<CFELSEIF gmt GT 0>
<CFSET gmt = "+" & gmt >
</CFIF>
<CFHEADER NAME="Expires" VALUE="Mon, 06 Jan 1990 00:00:01 GMT">
<CFHEADER NAME="Pragma" VALUE="no-cache">
<CFHEADER NAME="cache-control" VALUE="no-cache, must-revalidate">
<CFHEADER NAME="Last-Modified" VALUE="#dateformat(now(), 'ddd, dd mmm
yyyy')# #timeformat(now(), 'HH:mm:ss')# GMT#gmt#">
