Mason component to output image

I want a mason component to output a jpeg. This is what i've tried:

in httpd.conf:

 

 AddType image/jpeg .mjpg

 

in test.mjpg

<%perl>

open(FILE,"/robot.jpg");
while(<FILE>){
 print $_;
}
close FILE;

</%perl>

Running the component just spits back the code within test.mjpg.

Any ideas?
