No. The output of your CGI, no matter what, should only send one 
header. That header should reflect what's being returned to the user. 
So, if your CGI returns an HTML document, the header should include 
the line
    "Content-type: text/html\n\n".

Your browser will do the right thing when it interprets the HTML. If 
it encounters "<IMG SRC="..." >, the browser will send a follow-up 
request to the server to get the image.

If the _only_ thing returned by your CGI is an image, then use
    "Content-type: image/gif\n\n"
or whatever is correct for the type of image being returned.

HTH.
