Hi Brian, yes that's right -- in fact that *is* what you were looking at,
but we did it so cunningly you couldn't tell. ;) The issue is getting the
divs to load in the right order.

We are already relying on that as it's less than 1% of people now.

We appreciate your feedback, but don't you feel static thumbnails would
completely lose the virtual 'scroll' along the street that the user can do?

Broadband is only getting more common.

They already use progressive which looks very good in Firefox, but we agree
IE doesn't take advantage :(

Can we ask your connection speed? How long did it take to load roughly?

Yep, still in beta but all good points.

What would you suggest instead of the 3 tables on the page? Do these really
add a lot to the load time do you think?
