captchas will have a 'url' field which should be loaded as the image.
'type' and 'mime' will vary, and probably shouldn't be used too
closely.
Some captchas (iirc ReCaptcha) won't give you easy access to the image.
And this plan won't be compatible with the variety of new captcha types
like the KittenAuth-like category of CAPTCHAs.
Differentiating between the types just to support text CAPTCHAs (which are
really the easiest CAPTCHAs to break) also sounds unfortunate.
We might just have to do something that outputs a blob of html or a url to
a html document (either perhaps as a frame url or a url to fetch the blob
of html from).
