I have a drawing in Google Docs Drawings, and I would like to embed a PNG/GIF of it in a web page, but I would like the embedded image to remain up to date with any changes made to the drawing.

Is there a way to do this? It wouldn't matter if the image was only updated once per day or something, by the way.

Ideally I would like something like this:

    <img src="docs.google.com/drawing/png?docid=123456789123456789&width=400&height=200"/>
