Ok, you are trying to deliver the image inline. That requires a different
document type in your header. Look at
http://wp.netscape.com/assist/net_sites/pushpull.html. Search for
multipart/mixed on the page. There is a brief description and an example that
should help you get this done.
Another way would be reference the script that produces the image as the source
for the image. Pass the text as part of the query string. When your script
returns the image, include the header ("Content-type: image/jpeg") followed by
the image. Do not send any other content. I find this method a little easier to
manage.
Let's call your script "makeimage.php", your variable name "text" and the text
to show "A sample string". Include an image tag in the page you are returning:
<img src="makeimage.php?text=A sample string">
You can test the image appearance by going directly to:
http://www.yourdomain.com/makeimage.php?text=A sample string
I hope this make ssome sense to you.
