Subject RE: Generating images on-the-fly (newbie question)
Date Thu, 10 Oct 2002 00:30:32 GMT
Daniel, 

You should be able to do something like this. I haven't tested this
example,
but I've done this before on code I no longer have access too.

In your page: <img src="me.html?your=params&go=here">

In me.html, have a block of Emberl like the following. The first [ will
have to be
the very first character. Otherwise, any whitespace inbetween will
become part of the image
which will corrupt it. 

[- 
$http_headers_out{'Content-Type'} = "image/gif";

$gifdata = .... ; # GD generated image

binmode OUT;
print OUT $gifdata;

exit;
-]

help,
