Finally I found some solution with this script:
</SCRIPT>
<SCRIPT TYPE="text/javascript">
<!--
SLIDES = new slideshow("SLIDES");
SLIDES.timeout = 4000;
SLIDES.prefetch = -1;
SLIDES.repeat = true;
s = new slide();
s.src = "http://ent52.sharepoint.hp.com/teams/lean_assessment_tool/Pictures/See%20Q%20policy.png";
s.text = unescape("");
s.link = "http://intranet.hp.com/panhp/Quality/Pages/index.aspx";
s.target = "_blank";
s.attr = "width:420,height:230";
s.filter = "progid

XImageTransform.Microsoft.Slide()";
SLIDES.add_slide(s);
s = new slide();
s.src = "http://ent52.sharepoint.hp.com/teams/lean_assessment_tool/Pictures/See%20Org%20and%20Proc.png";
s.text = unescape("");
s.link = "http://ent52.sharepoint.hp.com/teams/lean_assessment_tool/SitePages/HP%20EMEA%20processes%20colored.aspx";
s.target = "_blank";
s.attr = "width:420,height:230";
s.filter = "progid

XImageTransform.Microsoft.Slide()";
SLIDES.add_slide(s);
s = new slide();
s.src = "http://ent52.sharepoint.hp.com/teams/lean_assessment_tool/Pictures/See%20New%20Q%20site.png";
s.text = unescape("");
s.link = "http://intranet.hp.com/panhp/Quality/Pages/index.aspx";
s.target = "_blank";
s.attr = "width:420,height:230";
s.filter = "progid

XImageTransform.Microsoft.Slide()";
SLIDES.add_slide(s);
s = new slide();
s.src = "http://ent52.sharepoint.hp.com/teams/lean_assessment_tool/Pictures/See%20HP%20Lifecycle.png";
s.text = unescape("");
s.link = "http://ent52.sharepoint.hp.com/teams/lean_assessment_tool/SitePages/Quality%20lifecycle%20Home.aspx";
s.target = "_blank";
s.attr = "width:420,height:230";
s.filter = "progid

XImageTransform.Microsoft.Slide()";
SLIDES.add_slide(s);
if (false) SLIDES.shuffle();
//-->
</SCRIPT>
<P>
The problem now is when I click to open a link in new window it opens new window but that window cannot be maximized (has fixed size!). How to fix that?!
