Hotlinking: What do i output from my cgi?

i have a cgi program to stop people from hotlinking an image from my site.

my simple website to be protected is as follows:
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<img src=http://www.mywebserver.com/~user/cgi-bin/myprogram.cgi?../images/figures.png">
</body>
</html>

my cgi accepts ../images/figures.png as an input parameter.
it checks the HTTP_REFERER is http://www.mywebserver.com

This is not the problem though.

My problem is what i must write as outtput from my cgi.

I think as a first line i must output:

Content-type: image/png
i simply want the page to be generated as:

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<img src="../images/figures.png">
</body>
</html>

My program is written in pascal so i dont want perl code.... all im asking is what i should output from my cgi... as a said i think the first line of output should be:

Content-type: image/png
Then i dont know what must follow
