There have been big changes since Pub 98. One being that when you Publish to
the Web or Save As a web page in Publisher 2007, you will get filtered html.
Filtered code is the less bloated, cleanest, fastest loading code. One of
the biggest differences is that by default setting you will get an index.htm
file (your home page) and an index_files folder that contains all your other
pages and supporting graphics and images. Pub 98 did not use a subfolder.
You upload both the index.htm file and the index_files folder to your host.

You might want to take a few minutes and read about the evolution. There are
other changes...
