Using hot spots is probably the way I would go, and I would set it up like this:
<img src="image.gif" width="170" height="41" usemap="#Map" border="0">
<map name="Map">
<area shape="rect" coords="3,2,83,32" href="admin.php?table=public">
<area shape="rect" coords="88,5,158,35" href="admin.php?table=private">
</map>
Then for the admin page:
$table = $_GET['table'];
if(iset($table) && $table == "private")
{
.....private table......
}
if(iset($table) && $table == "public")
{
.....public table......
}
Hope that helps,
