Are you trying to emulate filling out a real form? If so, how does the HTML
for the entire <form> look like?

First, you should separate 'image' from the other fields using a '&' letter.
Secondly, it looks very odd that anyone would use a "standard" form to allow
anyone to post an image to a site. I've never seen it used like this.

I've read the PHP/CURL module source code, so I know this instead turns the
post into a multipart formpost which is a totally different way of sending
the data to the remote host. The host was most likely programmed to just
receive one kind of POST, so you cannot simple pick one you like, you need to
use the one the receiver expects.

Nope, you won't be able to do that. It is used differently.

I'm not a PHP hacker, but I know my way around in the curl world.
