PPI is an *output* or *display* parameter. Perhaps what they
mean is that the image will be displayed at 72 PPI - which is
what most monitors are geared for. They should be able to give
you the pixel dimensions in HxW that will lead to a properly
sized image in their displayed page.

Bottom line - this shouldn't be your concern and makes no sense
for most raster graphic files anyway as you can't specify it in
the internal formats of most of the standard raster image formats.

Empirical data are always better than theoretical data.

Pixels/inch is meaningless for on-screen display and often
misunderstood (apparently even by the developers at Amazon.com). All
that matters for on screen display is final dimensions, such as 120x30
pixels.

PPI (also call dots per inch (DPI)) is ONLY meaningful when printing
an image. It tells the printer what the final size of the image being
printed should be. So if you saved your 120x30 JPG as 120DPI (or
PPI), the image would print 1" by 1/4" in size.

If you told it it was 60 DPI, it would print at 2"x1/2" in size, with
reduces quality, however, since your image still only contains 120x30.

ok I am working on getting a tool up on amazon. they use excel for all of the
info.
they want the pictures 72 pixels per inch.
but if I use say acdsee to change a picture I cant' really choose the ppi. how
do I edit the pics to get the right resolution? they don't give a max size so I
can use a decent size picture.

I use ACDSee and I also don't know any way of controlling the PPI. I also
use Photoshop, which will certainly do it, but that would be overkill. I
have Jasc Paint Shop Pro, which can do it and can be had for cheap.

Steve,

If you have any of the Microsoft Office products, they come with Microsoft
Photo Editor and it's really handy for resizing, cropping and if you choose
"File->Properties" it brings up a dialog box that you can change the PPI --
I tried it and it works (from 300 to 72 in my example).

figures (G)I just made the pic the regular size sent it to them and they said it
was fine.

This isn't something you really need to worry about. Most monitors
are in the 72-100 ppi range anyway, so how it looks on your screen is
pretty much what everyone else will see anyway.

But you can do the math in your head pretty easily. A 150 pixel image
would be about 2 inches. Normal reading text is 15 pixels per line or
so, or about 5 lines per inch, so you can figure your image sizes
accordingly.

Note that the PNG image type does allow for specifying the pixels per
inch within the image data, but not all web browsers support PNG yet
(most do).
