Sadly this is not the pitfall (I think). The images are in

app/
  public/
    images/
      foo/
        a_1.gif
        a_2.gif
        a_n.gif
        b_1.gif
        b_2.gif
        b_n.gif
      bar/
        a_1.gif
        a_2.gif
        a_n.gif
        b_1.gif
        b_2.gif
        b_n.gif

If I get access them directly as in /app/images/foo/b_1.gif or
/app/images/bar/b_3.gif it all works fine. However, I want to instead
query for /app/<foo|bar>/<a|b>/<\d>. Then, if the image exists, just
send it back, else create it and send it back.

My sense is that it is not possible to send an image back as a result
of an ajax query. An ajax query can only return text, json or html
(all different kinds of text, really). I am assuming that send_file()
sends a binary stream back that the browser has no way of handling as
a result of an ajax request.

Am I right or wrong?
