Umm, you can't send your html and image as part of the same data stream.  
They have to be two separate data streams, in response to two separate 
HTTP requests.

ie, user requests page, you send:

Content-type: text/html


<img src="script.php?send-image">

user requests script.php?send-image, you send:

Content-type: image/png

image data here

You're trying to send both in a single HTTP response.

They said the same thing about Urkle; that little snot.  Boy I'd like
to smack that kid.
