In order to get
graphics to behave
themselves on the
web, we first have
to compress them to
take up as little
room as possible, so
that it takes as
little time as
possible for the
viewer to download
them. Opinions vary,
but most people
believe that above
50K is getting too
big, particularly if
you combine several
images on a page.
In all cases, you
may want to modify
the images, such as
to adjust the
brightness or
contrast, to crop
them, or to scale
them. Scanners and
digital cameras
usually come bundled
with software to
help you do these
modifications.
Remember, most
images will end up
just a few inches
square, at most, on
the computer screen
on your web site:
that is just 300 by
300 pixels, at about
72 dots per inch
(DPI). Having a 1280
by 1280 image from
an expensive digital
camera will be of
little benefit over
the 640 by 480 image
of an inexpensive
one. Except in
special cases
showing particular
products, you need
to scale all of the
images down before
getting them to us.
For the best
graphics for your
site, we suggest
that digital photos
be taken at a low
resolution like 640
x 480. Images you
scan should be
scanned at a lower
resolution such as
100 dpi.
We would like for
you to provide your
graphics for your
site in .gif or .jpg
formats. You may
email
them to us or
provide them to us
in disk form.
We will be happy to
scan, crop,
manipulate or
further edit photos
for you at an
additional charge. |
