Hi

I wonder if anyone can help me, the following website http://www.parkerinternational.co.uk/ looks great when i view in live view in dreamweaver but when i view in ie or firefox the logos on the header goes funny and the twitter image does not appear

I really cannot understand what is going on, here is the header code

<meta http-equiv="content-type" content="text/html;charset=ISO-8859-1" />
<meta name="google-site-verification" content="eOODV4BJPCpl-NswV6_Qs_kd4HQD_5PrEqmdnxST12E" />
<link href="inc/css/default.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="inc/js/javagallery.js"></script>
<script src="inc/js/cufon-yui.js" type="text/javascript"></script>
<script src="inc/js/Avenir_LT_Std_700.font.js" type="text/javascript"></script>
<script type="text/javascript">
Cufon.replace('h1');
Cufon.replace('h2');
Cufon.replace('h3');
Cufon.replace('.telephone');
</script>
<script type="text/javascript">
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{
alert(alerttxt);return false;
}
else
{
return true;
}
}
}

function validate_email(field,alerttxt)
{
with (field)
{
apos=value.indexOf("@");
dotpos=value.lastIndexOf(".");
if (apos<1||dotpos-apos<2)
{alert(alerttxt);return false;}
else {return true;}
}
}

function validate_form(thisform)
{
with (thisform)
{
if (validate_required(name,"Your name must be filled out!")==false)
{name.focus();return false;}



if (validate_required(email,"Your E-mail must be filled out!")==false)
{email.focus();return false;}else{
if (validate_email(email,"Your E-mail is not valid!")==false)
{email.focus();return false;}
}
if (validate_required(phone,"You must fill in your phone number!")==false)
{phone.focus();return false;}


}
}

</script>
