I have successfully used this construct:

    <mediaobject>
      <imageobject>
        <imagedata fileref="diagram.eps" format="eps">
      </imageobject>
      <imageobject>
        <imagedata fileref="diagram.jpg" format="jpg">
      </imageobject>
    </mediaobject>

The eps image gets used in the PDF output, the jpg image gets used in the HTML
output.
