Just did a test.. sadly (and logically) sections that use images or graphs turn up bare, but overall this looks pretty useful! Especially for moments when you just need a quick blast of info.

Yes, unfortunately that's one limitation of the (experimental) API cleartext extension. It'd be really nice if they converted the image to an URL, but alas! no such thing. Just made me realize that I'll make a request for such a feature to Wikimedia ASAP..
