you could just use a script that detects what res they are using and redirect them to an appropriate page. not to sure how to just change the background picture though.  To redirect them just use something like

code:

---

<script language="JavaScript">
<!--
if ((screen.width>=1024) && (screen.height>=768))
{
window.location="highres.html";
}
else
{
  window.location="lowres.html";
}
//-->
</script>

---

enter whatever values you want for the width and height
