IE8 & large images --- !!

[PF Marconi]

I'm new to CSS and am using a 2 col fluid layout. I've encountered 2 problems using the DD code - and am lost as to why.

PROBLEM 1.

The background was repeating well below the bottom of any text - I've made it "no-repeat" so now just have a black bg at the bottom.
I believe the thumbnails are pushing the page down but I don't know how to sort it out.
I've overcome the problem in a rather cack-handed manner by making the bg "fixed", rather than scrolling.

PROBLEM 2.
Works fine in FF. However, everything changes in IE8. The thumbnails are fine and the enlarged images remain good on margin-top:100px.

HOWEVER - the enlarged images move to the right and cover some of the thumbnails!

I'd be very grateful for any advice.
Code below.

Thanks
Paul

do you have this page online somewhere so we can see the problem in action?

I can try to recreate your page when I get home, but you'd get a quicker response if we could see the problem right away.
