Dear all,

I'm very appreciative of every suggestion on how to preparing high-resolution pics on one page (PDF format).
Very thankful to the following people for their timely help:

Prof. Ohlendorf, D. H., 
You can use Photoshop to extract the page that contains th poor images. Replace 
the images inside Photoshop, flatten and write a PDF file for that page. Then 
use Acrobat to replace the page in the original file.

Dr. Zhang, W.
The best thing to include color figures in .pdf file is to use Adobe
illustrater. This is a powerful program to produce .pdf and .ps files.
Basically, you need a postscript printer driver installed. Produce .ps
file from your word document, then modify the labels in Adobe illustrater.

Dr. Constantinescu, A. T.
Two suggestions: good ways to place hi-res. images in a PDF file
are TIFF and EPSF.  TIFF is 24-bit raster format, so you have 8bits for
each of Red Green and Blue.  Don't know exactly for EPSF (which is also
raster type), but it's the choice of all people working with LaTeX.
However, don't make them more than 300dpi for inclusion in PDF files:
these files will be used just for working printouts.  If your paper gets
accepted (good luck!), then you will have to submit higher-resolution
images separated from the text.  Render them such that you get a
certain size at 300dpis!  In order to do this, make the following
things: 
- think about how big the image would you like to be when printed out
  (cm x cm or inch x inch)
- multiply each dimension by 300.  This will give you the "resolution"
  (better said the size) you will have to generate the images at.
- get the output image, load it in Photoshop (or whatever you want) and
  set their resolution (which usually is 72dpi) to 300dpi.
- when you load them in Word, they should need no further scaling,
  neither up, nor down.
Say you would like to have an image 5 x 5 cm.  This means 1.96 x
1.96 inches, so 590 x 590 pixels.
Now, the second thing that can go wrong: if you use Acrobat
Distiller (or PDF writer) and you use TIFF images (and not EPSF; I never
used EPSF, but heard that people using it had not this problem).  Start
the Acrobat Distiller program ("Start Menu/Programs etc", you get the
picture).  Check the "Job options".  You will have there information
about the document resolution and the resolution different images will
be rendered at (that's a separate tab).  Check that you don't have there
72dpi!

Dr. Kursula, P.
I think I did this by changing the settings for the pdf writer. Somewhere
there you will find the option of using compression for your images. Turn
it off, and your pictures will be the same quality as the originals (and
the pdf file much larger of course!).

Dr. Wiesmann, C.
you can use Adobe Illustrator or Adobe Photoshop. If you use "file
place" instead of "insert picture" you'll have more than one image on
one page. Save then as pdf.

Dr. Chen, Y. W.
I guess you need to use Adobe Acrobat.

Dr. Bosch, J.
you can simply use Acrobat (the full Version) to this. In Acrobat Destiller you have severall Options for the
quality of the pdf file.
Off course the higher the resolution the bigger your file will be.
The easiest way of using the Destiller, is to create a regular postscript file of your pictures and then
convert them to a pdf in a higher
resolution e.g 300 dpi. As you might know ps files are vectorized, therefore you can scale the files up in pdf.
Not sure if this suggestion helped you ?

Good lucks to everyone!
