Some websites have a script in place that will fetch information from a database and feed it via a PNG image.
Does anyone know what this is called and where I might find a suitably easy version to start having a play with?
.:EDIT:.
What I mean is some websites have a forum add on that will serve an image with information about your profile on it -

Similar to how MyGamerCard.net works when it pulls GamerTag info and serves a PNG and has the stats as part of the image.
