You know that HTML cannot include an image directly into a page.. It must always go via an URL.
Thus, you script must make the generated image avaiblable via an URL and return the URL to the image.
Yes. And that's the problem :-)
I may store the image in a transient container buried in a temporary folder ... Did it once in the session, but this is gross.
I'm interested. Why is this a problem (storing an image in the session)? I think the java guys store things in sessions all the time (not that this is an argument here ;))
A session is per-user, while my images aren't, so there's a small overhead for too many generations. Furthermore, I expect they'll be harder to invalidate when the things to draw change
