   Note: You can change the image name and file path on the first line below, or you could also use .
   
   Solution A: If you cannot use cfcontent
   
   

    <cffile action="readbinary"  variable="pic"/>
   		
   
   	
   		
   
   	<cfscript>
   		
   
   	
   		
   
   	context = getPageContext();
   		
   
   	
   		
   
   	context.setFlushOutput(false);
   		
   
   	
   		
   
   	response = context.getResponse().getResponse();
   		
   
   	
   		
   
   	out = response.getOutputStream();
   		
   
   	
   		
   
   	response.setContentType("image/jpeg");
   		
   
   	
   		
   
   	response.setContentLength(arrayLen(pic));
   		
   
   	
   		
   
   	out.write(pic);
   		
   
   	
   		
   
   	out.flush();
   		
   
   	
   		
   
   	// response.reset(); -optional for problems out.close();
   		
   
   	
   		
   
   	</cfscript>
   		
   
   	
   		
   
   	 

   Solution B: If you can use cfcontent
   

    <cfcontent type = "image/jpeg" file = "#ExpandPath('huge.jpg')" deleteFile = "No" reset="yes">
