That would be very odd if so. Take a look in your cache and for the
Richmond page you will find 6 sliced JPGs. Unless your browser has
Photoshop built in ;)

It's a good idea which we are already planning.

The site will work without a scrollbar at 1024 upwards, so your preferred
width must fall just a bit short of that. Oops, sorry.

We have struggled with this, but it is the optimum height from testing where
users felt they were getting a realistic experience. It also is the
absolute minimum where the smallest ePosters (120x60) actually fit in the
shops' windows. There are many other factors too. And just reducing them
what looks like a lot only resulted in a small reduction in file size. We
are also compressing them to 40%.

That is consistent with our market research. Also the general consensus is
anything under 15 seconds is acceptable to the user, anything more is a
worry. So, whilst we are glad you are within our target range on a shared
slow broadband :) we still want to make the page 'usable' if not fully
loaded, sooner.

The idea there is to present the first JPG slice ASAP, and the rest can
follow as the user doesn't need them until they scroll or cross the road.

Thanks, but for the future, what method do other designers use for
presenting such info as our instructions table etc.? There are a lot of
sites which load pretty graphic 'tables' around the page, but they are
usually divs. Is there a program they use to automatically create these
graphical elements and align them in WYSIWYG? E.g. our partners at
www.GreasyPalm.co.uk
