To look like photographs and not cartoons, photographs require a color
depth of at least 16-bits. Sometimes color depth is described in terms of a
color palette. For example, a graphic format with an 8-bit color depth is said
to have a 256-color palette.
Choosing file formats for graphics
One of the challenges of using photographs and clip art in Office files is
keeping file sizes to a minimum. A file that is loaded down with many
photographs can take a long time to load and send over the Internet.
The trick is to find a balance between high-quality, high-resolution graphics
and the need to keep file sizes low. Here are some tips for choosing graphic
file formats:
Consider sticking with clip-art vector graphics if you’re including
graphics in your file strictly for decoration purposes. Clip-art vector images
are easy to come by, don’t require very much disk space, and can be
edited in Office.
For photographs, make JPEG your first choice for graphics. JPEG images
have a fairly high resolution. JPEG is the de facto photograph standard
on the Internet.
If you’re dealing with black-and-white photos or resolution doesn’t
matter, use GIF files. These files eat up the least amount of disk space.

After you’ve weighed the merits of different kinds of graphics and decided
which one is best for you, you can insert it. To insert a picture, either use
one stored on your computer or get one from the Internet.
