Wow, that was not nearly as well-formatted as I had hoped. Hope it's
still comprehensible. In any case, the import parts are simply:
1. use Router::parseExtensions() to parse image extensions and pass
them to $RequestHandler (perhaps define the extensions array as a
model property to maintain DRY);
2. use $RequestHandler->setContent() to set the content-types for the
various extensions
3. and I forgot to mention this in the previous post, but copy the
ajax layout to /app/views/layout/image/default.ctp, and set $this-
>layout = 'image' in the controller action;
4. create simple pass-thru view(s) (since they're all the same, you
could just use something like $this->render('image') instead of
Router::parseExtensions()'s default view locations);
5. use $html->image instead of $html->tag; it will accept both strings
and arrays as image locations.
