You'd need your CFM file to use CFCONTENT to return a JPEG, and not return
anything else (no HTML tags or other text output).
<!--- joe.cfm --->
<cfif IsUserInRole("PictureViewer")>
<cfset ImageToShow = "go.jpg">
<cfelse>
<cfset ImageToShow = "blank.jpg">
</cfif>
<cfcontent type="image/jpeg" file="#ImageToShow#">

Unfortunately, it's pretty intensive, and I wouldn't recommend it in a
high-usage environment. There are alternatives, such as the use of symlinks
or junctions, or the use of web server authentication, that you can use to
offload this kind of thing from CF, if you're in that sort of environment.
