I'd do it with a role attribute myself

  <mediaobject>
    <imageobject role="print.hires"> ... </imageobject>
    <imageobject role="print.lores"> ... </imageobject>
    <imageobject role="online.hires"> ... </imageobject>
    <imageobject role="online.lores"> ... </imageobject>
  </mediaobject>

and then tweak the stylesheets to "do the right thing".

                                        Be seeing you,
