I'm using Publisher 2003

OK, so I am creating a webpage that currently has 7 pages.
Some of these pages happen to have the same picture on
them, but when I "publish to web" Publisher gives all of
the pictures its own name (something with numbers that I
can't make sense of) and I end up with the same picture 3
or 4 times with a different name.  This makes for more
pictures, thus more size for uploading.

Is there a way to tell publisher to just use the name the
file already has on my computer???  Or even to simply get
in and change the name of the picture in Publisher?
