Ahh now it becomes clear, you where trying to place the image inline.
There is a way with base64 encoding, but it isnt supported by many
browsers - you can actually say <IMG SRC="data:image/png,base64;[...]">
where the [...] is the base64 encoded image, so you would need to wrap
an ob start and ob end around your code to catch output, then base64
encode it then display it.
The problem is it dosnt work in IE because IE dosn't support this. Its
also not very nice for anyone not wanting to view images as they will
have downloaded the image even though they dont want to see it. There
was a very good reason why I know that and have done it, but more then
99.9% of the time, its not the way to go.
(the case in example was an embedded application on a machine that had a
pseudo-web interface but no webserver - it would wait for a connection
on a port then "dump" a stream of text which would be in HTML - there
was no webserver there it would ignore any http headers sent).
