I'm getting off topic. Please disregard the quoted paragraph.
Now, back to the first post in thread.

Solutions to this problem come in two flavors: client-side, where the 
server sends a list of URIs each associated with a media query; and 
server-side, where the UA sends a medium description to the server and 
the server responds with the correct message body. Which one to choose 
is a matter for debate in this thread.
Is the list to be embedded in the HTML? Is it to be sent as an entity 
body of a HTTP 300 Multiple Choices response, with due roundtripping, 
lag and compatibility issues? Is it not to leave the server at all, and 
the UA to send a medium description?
This issue is in no way limited to still images, and applies just as 
well to video and sound.
