php image problem

Hi all I am using a joomla website with a live support section. The live support is by live zilla.

When you visit the site [url]www.pristine-it.ie[/url] using internet explorer the live support image that indecates either online or offline only shows when it feels like it. I dont have this problem with firefox.

Have a look at the site using IE and flick back and forth through the menus and you will see what i mean.

Here is the code used to place the image and the code from the file that determins which image to show.

This is the code entered in to the joomla site.

<!– [url]http://www.LiveZilla.net[/url] Chat Button Link Code –><a href=”javascript:void(window.open(‘http://www.pristine-it.ie/support/livezilla.php’,”,’width=600,height=600,left=0,top=0,resizable=yes,menubar=no,location=yes,status=yes,scrollbars=yes’))”><img src=”http://www.pristine-it.ie/support/image.php?id=01” width=”150″ height=”139″ border=”0″ alt=”LiveZilla Live Help”></a><noscript><div><a href=”http://www.pristine-it.ie/support/livezilla.php” target=”_blank”>Start Live Help Chat</a></div></noscript><!– [url]http://www.LiveZilla.net[/url] Chat Button Link Code –>

This is the code to retrive the appreate image.
