Indeed, you can receive the image data alright, but it's no use in your
JS code. There is not much you can do with the data currently. On the
other hand, image objects just take URLs to get the image into the DOM.
So I think you have to do two steps, instead of one:
1) generate the image with a POST request, but leave it on the server
and just return the URL to it
2) use this URL as the source attribute in an image object
