Leave any extra copies of the images alone...don't delete.

Okay - with 500 plus images that resizing thing is probably a long term
project ... in the meantime, what happens if I just delete the gif files
once
I have uploaded? I have tried it with one & it still seems to wrk, but
maybe
it wouldn't be visible through firefox. On the other hand, if a browser
is
choosing which of the two images to view, does it really matter that there
are two versions - it might add to my upload time, but not to my viewers
download time ...?

The more pictures you have on a page the larger it will be. While Rob
might
be correct about 40kb being a good goal for FP websites, that is probably
unrealistic for Publisher pages. FP produces more efficient code, than
Publisher. I think that if you can stay under 100kb for a Publisher page
with pictures, you are doing great. That page will load quickly enough to
keep the interest of the viewer. Publisher also tends to load text rather
quickly and before pictures, so I would feel good about 80kb, especially
if
you originally had a 200kb image on that page. Just keep in mind the
principle that the smaller the file size, the faster the page will load.
If
you have a lot of images, the page will take longer to load. Just avoid
lots
of large pictures. This is what optimization is all about.

Part of the reason for larger file sizes is that as you discovered,
Publisher sometimes makes multiple copies of the inserted images with the
goal of providing the "best" image version for the browser used....with
mixed success. Unfortunately that can mean the low resolution gif copy is
loaded in FireFox. I have found that if you not only optimize the
resolution
of the image but also resize the image before inserting it into the
Publisher page, such that the image is displayed at 100% scale, Publisher
usually will not make the lower resolution copy for FF...it will use the
better quality image for all browsers.

As an example, say you insert a full size, high resolution image taken
directly from your digital camera into a Publisher page. You then reduce
the
image box to fit your page layout design. If you right click the image >
format picture > size tab, you will see the height and width of your
image
box under "Size and rotate". If you look under "Scale" you will see what
%
the image is at. Then go back to your original image and reduce the
resolution to 96dpi, and resize the dimensions of the image to agree with
the dimensions of your picture box. Then insert this new optimized and
resized image and set the scale at 100%. Publisher will then use the one
image for both FF and IE, you won't get the lower resolution copy and
your
image will be at the best quality and smallest size...in other words, it
will be optimized for your Publisher built webpage.

If the extra step of resizing the dimensions of the image in the image
editor to fit the text box is more than you want to do, then at least
reduce
the resolution of the image. That alone is most important for improving
loading speed. For the best quality, also resize the image such that you
can
display it at 100% scale.

okay - I have done all that - even the "tiresome" image downsizing -
but
the
web pages still come out at 80kb. It seems that publisher is saving
both
a
gif and a jpg version of my images in the "index file" which is
doubling
the
size. why? do I need both? can I just delete one of them? thanks.

Like Rob I also feel that 200kb is still too large for a web image,
unless
perhaps if it is a full page image, but even then you should be able
to
reduce it to a fraction of that. It may be too "tiresome" for you to
do
it
the right way in an image editing program, but then it will also be
too
"tiresome" for people viewing your site to wait for such a huge
picture
to
load, and they will move on to another site. It would take around a
full
minute for a 200 kb image to load for a dial-up connection.

Go there to get an idea of how long it takes for your site to load and
perhaps rethink how "tiresome" it will be to optimize your images so
that
people will actually stay around long enough to view the site.

Thanks David - I have made sure the two buttons are unchecked ...
the
strange thing is that I have used "change picture " on a page which
is
compressing & inserted the non-compressing image - no problem, it
compresses
fine; similarly, substituting the compressing image on the
non-compressing
page &it doesn't compress, so it would appear the problem is with
the
pages
rather than the images - each page is a seperate document for
various
ease-of-handling reasons. The original image size for both pages is
approx
4MB - compresses to 200kb when it works ... I know I can use other
software
to compress, but that would be very tiresome ... and the point is it
should
work! don't like to leave an unsolvable mystery!!!!

When you use the Compress feature, you can choose to compress the
images
on
one page or the whole document. Try the whole document....or now,
the
pages
where the images appear to not be compressed.

Some images may already be as compressed as they can be by this
method.

In some cases your design may result in images being combined with
other
design elements to produce other combined images. Also, if you use
non-web
fonts, those text boxes can be converted to images, thus increasing
your
overall file size. Some of these design mistakes can be found by
running
the
design checker tool.

Be sure to go to Tools > Options > Web tab and uncheck "Rely on
VML..."
and
"Allow PNG...".

For optimal results resize and optimize your images in a third
party
image
editing program before you insert them into the Pub document, and
size
them
at 100%. If you don't have an image editing program a popular
freebie
is

I am using publisher 2003 to construct my website - lots of pretty
pictures
so I am using the compress pcitures button to keep the file size
smaller -
it
seems to work for some pages & not for others even if they are
very
similar -
does anyone else have this problem ???? & a solution????
