Using WordPress to post from a flash app

Hey, I am trying to figure out if there is a way via plug-in or just in the basic API that will allow me to have a game create a blog post and upload an image?

To explain more in depth, we are creating a game that will generate an image after a bit of work from the user, and we would like to have the results posted to our blog under a specific category. We know using Flash it’s possible to post to WordPress, but can we have it upload an image and post?

If there are links to documentation on this, this would be great.
