Hello,
I have created some very basic javascript to change a large image based on the thumbnail that the mouse pointer is currently over:
http://www.thorntonlodgefarm.co.uk/new/test.shtml
This works on my installation of IE6, Netscape, Opera, Firefox and Mozilla - but I have seen it fail on two installations of IE6 so far, the large image fails to appear altogether and a javascript error is produced - "...is null or not an object...".
Any ideas?
