well, you simply need as many images as you want to serve to your users,
right??  if you *don't* want to send the same image to a mobile phone
*and*a desktop browser, then you need at least two different images...
*how many* different images is completely up to you, your client, and your
user base.

to this end, the only real solution would be a new image format, one that
somehow knows the screen size it is being loaded into, then downloads and
displays the correct image for that scenario.  something like Yoav
discussed here:
http://www.yoav.ws/2013/09/Responsive-Image-Container

or maybe in PS, when saving for the web, you could create the different
"cuts", which would be included in a single image's meta data, then
communication between the browser, the server, and the image could send
just what you want, based on that single scenario.

but i don't see *that *happening in my lifetime...
