I wrote a SASS mixin to do this with PollEverywhere and it works well.

=mobile-image($name, $background_position: 50%)
  background: inline-image('../images/#{$name}.png') $background_position no-repeat

  @media all and (-webkit-min-device-pixel-ratio: 1.5)
    background: inline-image('../images/#{$name}@2x.png') $background_position no-repeat
